DETAILED DESCRIPTION

Example embodiments will now be described more fully with reference to the accompanying drawings, in which some example embodiments are shown. Example embodiments, may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey concepts of example embodiments to those of ordinary skill in the art. In the drawings, the thicknesses of layers and regions are exaggerated for clarity. Like reference numerals in the drawings denote like elements, and thus their description will be omitted.

Hereinafter, a unit for removing foreign matter and an apparatus and method for semiconductor packaging using the same according to some example embodiments of the inventive concepts will be described more fully with reference to the accompanying drawings, in which some example embodiments are shown. Example embodiments, may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey concepts of example embodiments to those of ordinary skill in the art. In the drawings, the thicknesses of layers and regions may be exaggerated for clarity. Regarding the reference numerals assigned to the elements in the drawings, it should be noted that like reference numerals are used for like elements. Also, in the description of example embodiments, detailed description of well-known related structures or functions are not provided when it is deemed that such description will cause ambiguous interpretation of the inventive concepts.

It will be understood that when an element is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present. As used herein the term “and/or” includes any and all combinations of one or more of the associated listed items. Other words used to describe the relationship between elements or layers should be interpreted in a like fashion (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” “on” versus “directly on”).

It will be understood that, although the terms “first”, “second”, etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of example embodiments.

Spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “below” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises”, “comprising”, “includes” and/or “including,” if used herein, specify the presence of stated features, integers, steps, operations, elements and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and/or groups thereof.

Example embodiments are described herein with reference to cross-sectional illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of example embodiments. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, example embodiments should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. Thus, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of example embodiments.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which example embodiments belong. It will be further understood that terms, such as those defined in commonly-used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

The semiconductor packaging device according to some example embodiments of the inventive concepts may include a process unit for performing a semiconductor packaging process and a foreign removing unit provided in the process unit to remove foreign matter remaining on an object to be processed.

According to an example embodiment, a semiconductor packaging device may be a dicing tape attaching device. The dicing tape attaching device may include a process unit (i.e., a dicing tape attaching unit) for attaching a dicing tape on a polished back surface of a wafer and a foreign matter removing unit for removing foreign matter remaining on the polished back surface of the wafer.

According to another example embodiment, a semiconductor packaging device may be a semiconductor chip attaching device. The semiconductor attaching device may include a process unit (i.e., a semiconductor chip attaching unit) for attaching semiconductor chips separated into an individual unit from a wafer to a wiring substrate and a foreign matter removing unit for removing foreign matter remaining on a wiring substrate and/or semiconductor chips.

According to another embodiment, a semiconductor packaging device may be a wire bonding device. The wire bonding device may include a process unit (i.e., a wire bonding unit) for electrically connecting semiconductor chips attached to a wiring substrate to terminals of the wiring substrate and a foreign matter removing unit for removing remaining on the wiring substrate and/or the semiconductor chips attached to the wiring substrate.

(Dicing Tape Attaching Device)

FIG. 1 is a plan view of a semiconductor packaging device 100 according to an example embodiment of the inventive concepts.

Referring to FIG. 1, the semiconductor packaging device 100 may be a dicing tape attaching device, but example embodiments are not limited thereto. FIG. 1 illustrates the semiconductor packaging device 100, such as a dicing tape attaching device, includes a dicing tape attaching unit 120 and a foreign matter removing unit 140. The dicing tape attaching unit 120 attaches a dicing tape on a polished back surface of a wafer W. The foreign matter removing unit 140 may remove foreign matter (e.g., particles and/or debris) remaining on the polished back surface of the wafer W before the dicing tape is attached. Also, the foreign matter removing unit 140 may remove foreign matter remaining on a wafer chuck 122 on which the wafer W is placed.

The dicing tape attaching unit 120 includes the wafer chuck 122 and a dicing tape attacher 124. The wafer chuck 122 may be disposed at a center of a chamber 110. The wafer W is placed on the wafer chuck 122 to allow the polished back surface of the wafer W to face an upper side. The dicing tape attacher 124 may be a roller type attacher, but example embodiments are not limited thereto. The dicing tape attacher 124 may be disposed above a side of the wafer chuck 122 so that a length direction of a roller 125 around which the dicing tape is rounded faces a first direction I. The dicing tape attacher 124 may ascend or descend by a driving member (not shown) and be straightly moved in a second direction II perpendicular to the first direction I. The dicing tape attacher 124 attaches the dicing tape on a top surface of the wafer W while moving in the second direction II in a state where the dicing tape attacher 124 presses the top surface (i.e., the polished back surface) of the wafer W placed on the wafer chuck 122.

During the attachment of the dicing tape, foreign matter may cause cracks when foreign matter exists on the top surface of the wafer W because foreign matter can concentrate a pressing force of the dicing tape attacher 124. Thus, to reduce the occurrence of the cracks, the foreign matter removing unit 140 may be used to remove the foreign matter existing on the top surface of the wafer W before the dicing tape is attached. Examples of foreign matter include but are not limited to organic components such as rayon and nylon and/or metal components such as iron, nickel, chrome, aluminum, and titanium.

The foreign matter removing unit 140 may be disposed above a side of the wafer chuck 122 to prevent it from interfering with the dicing tape attacher 124. Also, the foreign matter removing unit 140 is straightly moved along the second direction II by a transfer member 160. The transfer member 160 includes a guide rail 162, a slide 164, and a connection member 166, but example embodiments are not limited thereto. The guide rail 162 is disposed at a side of the wafer chuck 122 to allow a length direction thereof to face the second direction II. The slide 164 is coupled to the guide rail 162 to straightly move along the guide rail 162. A driver (not shown) for providing a straight driving force may be disposed on the slide 164. The connection member 166 connects the slide 164 to the foreign matter removing unit 140.

The transfer member 160 straightly moves the foreign matter removing unit 140 in the second direction II in a space above the wafer chuck 122. The foreign matter removing unit 140 injects gas onto the top surface of the wafer W placed on the wafer chuck 122 to suck the foreign matter scattered by the injected gas.

FIG. 2 is a side view of the foreign matter removing unit 140 of FIG. 1. FIG. 3 is a bottom view of the foreign matter removing unit 140 of FIG. 1. FIG. 4 is a sectional view taken along line IV-IV′ of FIG. 2.

Referring to FIGS. 1 and 2 to 4, the foreign matter removing unit 140 includes a body 142, an injection member 144, a suction member 146, and a magnet member 148. The body 142 may have a rectangular parallelepiped shape, but example embodiments are not limited thereto. Also, the body 142 is disposed above an upper space of a side of the wafer chuck 122 to allow a length direction thereof to extend in the first direction I. The injection member 144 and the suction member 146 may be integrated with the body 142. The injection member 144 injects gas, e.g., air onto the top surface of the wafer W, and the suction member 146 sucks the foreign matter scattered from the top surface of the wafer W by the injected gas.

The suction member 146 includes a part 142-s of the body defining at least one suction hole 146-1 having a slit shape longitudinally defined in a length direction of the body 142 on a bottom surface of the body 142. The part 142-s of the body further defines a suction space 146-2 that is fluid-communicating with the suction hole 146-1 is defined within the body 142. A plurality of discharge ports 146-3a, 146-3b, and 146-3c are coupled to a top surface (or alternatively side surface) of the body 142 to connect the discharge ports 146-3a, 146-3b, and 146-3c to the suction space 146-2. A suction (not shown) is connected to the discharge ports 146-3a, 146-3b, and 146-3c by vacuum lines (not shown).

The injection member 144 includes a portion 142-i of the body that defines a plurality of injection holes 144-1 in the bottom surface of the body 142. The injection holes (or alternatively openings) 144-1 are arranged in a line parallel to the suction holes (or alternatively orifices) 146-1 on a bottom surface of the body 142. The injection holes 144-1 are inclined toward a suction region of the wafer W, in which a suction force of the suction hole 146-1 acts. The portion 142-i of the body further defines a buffer space 144-2 that is fluid-communicating with the injection holes 144-1 defined within the body 142. Inflow ports 144-3a and 144-3b are respectively coupled to left and right side surfaces of the body 142 to communicate with the buffer space 144-2. A gas supply (not shown) is connected to the inflow ports 144-3a and 144-3b by a supply line (not shown).

The magnet member 148 is disposed on the bottom surface of the body 142 so that it is disposed on a side opposite to those of the injection holes 144-1 with respect to the suction hole 146-1. The magnet member 148 may have a rod shape, but example embodiments are not limited thereto. The magnet member 148 applies a magnetic force to the foreign matter containing the metal components scattered from the top surface of the wafer W by the gas injected through the injection holes 144-1. The scattered foreign matter containing the metal components may be attached on the magnet member 148 by the magnetic force of the magnet member 148.

The gas supplied from the gas supply (not shown) is introduced into the buffer space 144-2 through a plurality of inflow ports 144-3a and 144-3b. The gas within the buffer space 144-2 is injected onto a desired (or alternatively predetermined) region of the top surface of the wafer W, i.e., the suction region of the wafer W, in which the suction force of the suction hole 146-1 acts, through the injection holes 144-1. The injected gas scatters the foreign matter remaining on the top surface of the wafer W. The scattered foreign matter may be sucked into the suction hole 146-1 by the suction force acting through the suction hole 146-1. The foreign matter sucked into the suction hole 146-1 may be discharged through the discharge ports 146-3a, 146-3b, and 146-3c via the suction space 146-2. A portion of the foreign matter containing the metal components of the scattered foreign matter is introduced into the suction hole 146-1 and the other portion is attached to the magnet member 148.

In the foreign matter removing unit 140 according to an example embodiment of the inventive concepts, the gas is injected into the suction region of the wafer W in which the suction force of the suction hole 146-1 acts. Thus, the scattered foreign matter may be introduced into the suction hole 146-1 along an air current due to the suction force of the suction hole 146-1. Accordingly, the suction member 146 may prevent the scattered foreign matter from attaching again to the top surface of the wafer W or from diffusing into the other region within the chamber 110.

(Semiconductor Chip Attaching Device)

FIG. 5 is a plan view of a semiconductor packaging device 200 according to another example embodiment of the inventive concepts.

Referring to FIG. 5, the semiconductor packaging device 200 may be a semiconductor attaching device, but example embodiments are not limited thereto. FIG. 5 illustrates the semiconductor packaging device 200, for example a semiconductor attaching device, may include a semiconductor chip attaching unit 220, and foreign matter removing units 240, 240′ and 240″, but example embodiments are not limited thereto and may include more or fewer foreign matter removing units. The semiconductor chip attaching unit 220 attaches semiconductor chips C separated from a wafer on which a dicing tape is attached into an individual unit to a wiring substrate P. The foreign matter removing units 240, 240′ and 240″ may remove foreign matter remaining on the wiring substrate P and/or the semiconductor chips C before a semiconductor chip attaching process is performed.

The semiconductor chip attaching unit 220 includes a guide rail 221, a transfer member 222, a supply vessel 223, a receiving vessel 224, an expander 225, and a chip bonder 226, but example embodiments are not limited thereto.

The guide rail 221 supports the wiring substrate P and guides the wiring substrate P transferred by the transfer member 222. The guide rail 221 is aligned so that a length direction thereof faces a transfer direction of the wiring substrate P, i.e., a first direction I and supports an edge of a side disposed along a length direction of four sides of the wiring substrate P. The transfer member 222 is disposed on the guide rail 221 to transfer the wiring substrate P supported by the guide rail 221 in the first direction I.

The supply vessel 223 is disposed at a front side of the guide rail 221 with respect to the first direction I. The receiving vessel 224 is disposed at a rear side of the guide rail 221. The supply vessel 223 receives the wiring substrate P to which the semiconductor chips C are attached, and the wiring substrate P within the supply vessel 223 is supplied onto the guide rail 221 by a separate supply member (not shown). The receiving vessel 224 receives the wiring substrate P to which the semiconductor chips C are attached and which is transferred along the guide rail 221.

The tape expander 225 is disposed at a side of the guide rail 221. Also, a wafer ring R for maintaining the semiconductor chips C is disposed on the tape expander 225. The tape expander 225 may be moved in the first direction I and the second direction II perpendicular to the first direction 1 by a driving member (not shown). The chip bonder 226 picks up the semiconductor chips C maintained by the wafer ring R to attach the semiconductor chips C on the wiring substrate P.

When the semiconductor chips C are attached to the wiring substrate P or stacked on existing semiconductor chips, foreign matter may cause cracks in the wiring substrate P and/or semiconductor chips C if foreign matter exist on a top surface of the wiring substrate P or a top surface of the semiconductor chips C. The foreign matter may cause cracks because foreign matter can concentrate a pressing force of the chip bonder 226 into the semiconductor chips C. Thus, to reduce the occurrence of the cracks, a plurality of foreign matter removing units 240, 240′ and 240″ may be used to remove foreign matter existing on the wiring substrate and/or the top surfaces of the semiconductor chips C before the semiconductor chips C are attached. The foreign matter may include but is not limited to organic components such as rayon and nylon and/or metal components such as iron, nickel, chrome, aluminum, and titanium.

The foreign matter removing units 240, 240′ and 240″ may be disposed on a plurality of positions disposed on the guide rail 221 and above the wafer ring R. The first foreign matter removing unit 240 may be disposed on a front end of the guide rail 240 to remove foreign matter remaining on the wiring substrate P transferred from the supply vessel 223 to the guide rail 221, but example embodiments are not limited thereto. The second foreign matter removing unit 240′ may be disposed on a standby position of the wiring substrate P between the front end and a rear end of the guide rail 221 to remove foreign matter remaining on the wiring substrate P that is in a standby state, but example embodiments are not limited thereto. The third foreign matter removing unit 240″ may be disposed above the wafer ring R to remove foreign matter remaining on the semiconductor chips C to be attached to the wiring substrate P, but example embodiments are not limited thereto. The foreign matter removing units 240, 240′ and 240″ inject gas onto the wiring substrate P and/or the semiconductor chips C and suck foreign matter scattered by the injected gas.

FIG. 6 is an enlarged view of a first foreign matter removing unit 240 of FIG. 5. FIG. 7 is a bottom view of the first foreign matter removing unit 240. FIG. 8 is a sectional view taken along line VIII-VIII′ of FIG. 6.

Referring to FIGS. 5 and 6 to 8, the first foreign matter removing unit 240 includes a body 242, an injection member 244, a suction member 246, and a magnet member 248. The body 242 may have a rectangular parallelepiped shape, but example embodiments are not limited thereto. Also, the body 242 may be disposed on a front end of the guide rail 221 to allow a length direction thereof to face the second direction II. The injection member 244 and the suction member 246 may be integrated with the body 242. The injection member 244 injects gas, e.g., air onto the top surface of the wiring substrate P, and the suction member 246 sucks the foreign matter scattered from the top surface of the wiring substrate P by the injected gas.

The suction member 246 includes a part 242-s of the body 242 that defines a suction hole 246-1 having a slit shape longitudinally defined in a length direction of the body 242 in a center of a bottom surface of the body 142. The part 242-s of the body 242 further defines a suction space 246-2 fluid-communicating with the suction hole 246-1 is defined within the body 242. A discharge port 246-3 is coupled to a top surface of the body 242 to connect the discharge port 246-3 to the suction space 246-2. A suction (not shown) is connected to the discharge port 246-3 by a vacuum line (not shown).

The injection member 244 includes a portion 242-i of the body 242 that defines injection holes 244-1a and 244-1b having a slit shape longitudinally defined in the length direction of the body 242 on both sides of the suction hole 246-1 defined in the bottom surface of the body 242. The injection holes 244-1a and 244-1b are defined parallel to the suction hole 246-1. The injection holes 244-1a and 244-1b are inclined toward a suction region of the wiring substrate P, in which a suction force of the suction hole 246-1 acts. The portion 242-i of the body 242 further defines a first buffer space 244-2a that is fluid-communicating with the first injection holes 244-1a and defined within the portion 242-i of the body 242. A first inflow port 244-3a is coupled to the top surface of the body 242 to communicate with the first buffer space 244-2a. The first inflow port 244-3a is connected to a gas supply (not shown) by a supply line (not shown). The portion 242-i of the body 242 further defines a second buffer space 244-2b that is fluid-communicating with the second injection hole 244-1b and defined within portion 242-i of the body 242. A second inflow port 244-3b is coupled to the top surface of the body 242 to communicate with the second buffer space 244-2b. A gas supply (not shown) is connected to the second inflow port 244-3b by a supply line (not shown).

The magnet member 248 is disposed on the bottom surface of the body 242 so that the magnet member 248 is disposed outside the injection holes 244-1a and 244-1b with respect to the suction hole 246-1. The magnet member 248 applies a magnetic force to the foreign matter containing the metal components scattered from the top surface of the wiring substrate P by the gas injected through the injection holes 244-1a and 244-1b. The scattered foreign matter containing the metal components are attached on the magnet member 248 by the magnetic force of the magnet member 248.

The gas supplied from the gas supply (not shown) is introduced into the buffer spaces 244-2a and 244-2b through the inflow ports 244-3a and 244-3b. The gas within the buffer spaces 244-2a and 244-2b is injected onto a predetermined region of the top surface of the wiring substrate P, i.e., the suction region of the wiring substrate, in which the suction force of the suction hole 246-1 acts, through the injection holes 244-1a and 244-1b. The injected gas scatters the foreign matter remaining on the top surface of the wiring substrate P. The scattered foreign matter is sucked into the suction hole 246-1 by the suction force acting through the suction hole 246-1. The foreign matter sucked into the suction hole 246-1 are discharged through the discharge port 246-3 via the suction space 246-2. A portion of the scattered foreign matter containing the metal components is introduced into the suction hole 246-1 and the other portion is attached to the magnet member 248.

In the foreign matter removing unit 240 according to an example embodiment of the inventive concepts, the injection member 244 injects gas into the suction region of the wiring substrate P in which the suction force of the suction hole 246-1 acts. The injected gas may scatter foreign matter. The scattered foreign matter may be introduced into the suction hole 246-1 along an air current occurring by the suction force of the suction hole 246-1. Thus, a foreign matter removal unit may prevent scattered foreign matter, which may act as a contamination source, from being attached again to the top surface of the wiring substrate P and/or diffused into the other region within equipment.
