This application is a Continuation of U.S. patent application Ser. No. 17/064,085, filed Oct. 6, 2020, which is a Continuation of U.S. patent application Ser. No. 16/124,838, filed Sep. 7, 2018, the entire contents of which are incorporated herein by reference.
BACKGROUNDIn some examples, electronic devices include a substrate (e.g., a dielectric material) and the substrate defines a cavity. A laser may remove (e.g., ablate) the substrate material in one or more specified locations to create the cavity in the substrate. A semiconductor die may be positioned in (e.g., recessed within) the cavity. The semiconductor die may include die contacts, and the die contacts may be exposed when the semiconductor die is positioned in the cavity of the substrate. For example, the semiconductor die may be positioned in the cavity and coupled with a surface (e.g., a bottom surface) of the cavity. The die contacts may face away from (e.g., in a direction perpendicular to) the surface of the cavity. The die contacts may be electrically interconnected with additional structures (e.g., a via or an electrical trace).
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
The present inventors have recognized, among other things, that a problem to be solved may include increasing the density of interconnections between a substrate and an electrical component (e.g., a semiconductor die) that is positioned in a cavity defined in the substrate. The present subject matter may help provide a solution to this problem, such as by providing a lateral trace that extends through a wall of the cavity. The lateral trace facilitates interconnecting one or more portions (e.g., a top side or a bottom side) of the electrical component within a footprint of the cavity. Accordingly, the lateral trace increases the density of electrical interconnections because the lateral trace allows for electrical interconnection within the footprint of the cavity. Further, because the lateral trace extends through a wall of the cavity, the lateral trace provides electrical interconnections in the same layer as the cavity. Accordingly, the number of layers of the substrate needed to interconnect with the electrical component may be reduced because of the increase in the interconnection density within the same layer as the cavity. Conversely, the number of layers of the substrate may remain constant, and the lateral trace facilitates the repurposing of the portions of the substrate that are no longer needed to electrically interconnect with electrical component. Accordingly, the performance of the electronic device is improved because of the increase interconnection density within the same layer as the cavity in the substrate.
An electronic device may include a substrate, and the substrate may include one or more layers. The one or more layers may include a first dielectric material and one or more electrical traces. A cavity may be defined in the substrate, and the cavity may be adapted to receive one or more electrical components. One or more lateral traces may extend through a wall of the cavity. The lateral traces may provide electrical communication pathways between the substrate and the electrical components.
As previously described herein, the cavity 120 is defined in the substrate 100. For instance, the second layer 110B may include the cavity 120. In an example, a laser is utilized to remove material from the substrate 100 (e.g., by ablating the dielectric material 102). The removal of the material from the substrate 100 by the laser forms the cavity 120. In another example, the cavity 120 is formed by mechanically removing the material from the substrate 100 (e.g., removing the material with a router, mill, or the like). In yet another example, and as described in greater detail herein, the cavity 120 may be formed with other manufacturing operations (e.g., one or more of the manufacturing operations described with reference to
The substrate 100 includes one or more lateral traces 140, for instance a first lateral trace 140A and a second lateral trace 140B. The lateral traces 140 may extend through a wall 125 of the cavity 120. In an example, and as shown in
The lateral traces 140 provide an electrical communication pathway within a footprint of the cavity 120 and facilitate the electrical interconnection with the substrate 100 inside the cavity 120. For example, and as described in greater detail herein, the lateral traces 140 may be in electrical communication with a pad 150.
The lateral traces 140 may be in electrical communication with the electrical components 210, and the lateral traces 140 may facilitate the transmission of one or more electrical signals between the electrical components 210 and the substrate 100. In an example, and as shown in
The lateral traces 140 allow for interconnection with the electrical components 210 in one or more directions (e.g., horizontally) with respect to the cavity 120. For example, the electronic device 200 may include a first via 130A and a second via 130B. The vias 130A, 130B may be coupled with the die 210A, and the via 130A may extend through (e.g., communicate with, interface with, intersects with, or the like) a first side (e.g., bottom side) of the cavity 120. The via 130B may extend through a second side (e.g., a top side) of the cavity 120A. The second lateral trace 140B may extend through a third side (e.g., a right side) of the cavity 120A. The third side of the cavity 120A may be perpendicular to the first side of the cavity 120A. Accordingly, the lateral traces 140 facilitate the interconnection of the electronic components 210 (that are positioned in the cavity 120) in one or more directions. In this example, because the lateral traces 140 extend through the wall 125 (shown in
As described herein, the substrate 100 includes the plurality of layers 110. The electrical components 210 (e.g., the die 210A, 210B) may be positioned in the cavities 120A, 120B and additional layers may be coupled to the substrate 100. The additional layers may cover the electrical components 210 (e.g., embed or encapsulate the components 210 within the substrate 100). In an example, a resistor may be positioned in the cavity 120A, and an inductor may be positioned the cavity 120B. The resistor and inductor may be coupled with the substrate (e.g., the second lateral trace 140B) and additional layers
As described herein, the electrical components 210 may be positioned in the cavities 210A, 210B of the substrate. In another example, the electrical components 210 may be coupled to an exterior of the substrate 100. For instance, a third die 210C may be coupled to a surface (e.g., a top surface) of the substrate 100, for instance with one or more solder balls. The third die 210C may be in electrical communication with the first die 210A and the second die 210B through the substrate 100. For example, the third die 210C may in electrical communication with the first die 210A through the via 130B. The third die 210C may be in electrical communication with the second die 120B through the via 130C. The first die 210A and the second die 210B may be positioned within a footprint of the third die 210C. For instance, as shown in
In an example, the coupling of the conductive layer 300 with the substrate 100 may create the lateral traces 140 or the electrical traces 104. In another example, the coupling of the layer of conductive material 300 to the substrate 100 may form one or more interconnects 310 (e.g., pads, contacts, sockets, or the like). The one or more interconnects 310 may be included in the vias 130 or the lateral traces 140. The one or more interconnects 310 may facilitate the interconnection of the electrical components 210 (shown in
The substrate 100 may be exposed to a light source, and the photoresist 400 may absorb light where the light passes through the mask. The photoresist 400 may harden if exposed to light, for instance in the specified pattern defined by the mask. The photoresist 400 that is not exposed to the light may be removed from the substrate 100, and the hardened photoresist 400 may remain coupled to the substrate 100 to thereby define a cavity region 410. In this example, the photoresist 400 is coupled to the conductive layer 300 outside of the cavity region 410 because the photoresist 400 is cured by the light (e.g., a positive photoresist). The conductive layer 300 may be exposed (e.g., visible, accessible, or the like) within the cavity region 410 because the uncured photoresist 400 is removed from the substrate 100.
A protective layer 420 (e.g., nickel) may be coupled to the conductive layer 300 in the cavity region 410. In this example, because the conductive layer 300 is exposed within the cavity region 410, the protective layer 420 may be coupled to the conductive layer 300. The protective layer 420 may shield (e.g., insulate, preserve, shelter, inhibit, cover, or the like) the conductive layer 300 within the cavity region 410 from additional manufacturing operations.
The selective coupling of the photoresist 600 may expose the via 130 and the protective layer 420. One or more openings 610 may be defined in the photoresist 600. For example, a first opening 610A may expose the protective layer 420. A second opening 610B may expose the via 130.
As shown in
The filler material 700 (e.g., copper) may be removed, and the protective layer 420 (e.g., nickel, titanium, tin, or the like) may prevent the further removal of material from the substrate 100 (e.g., the interconnects 310 or the lateral trace 140, shown in
In an example, a first solvent may dissolve the filler material 700 (e.g., copper). In this example, when the first solvent dissolves the filler material 700 (e.g., the filler material 700A), the first solvent will communicate with the protective layer 420. The first solvent may not dissolve the protective layer 420 (e.g., nickel), and the first solvent will not remove additional material from the substrate 100 (e.g., the protective layer 410 may be configured as an etch stop).
A second solvent may be applied to the protective layer 420 and dissolve the protective layer 420. The second solvent may not dissolve the structures shielded by the protective layer 420 (e.g., the interconnects 310 or the lateral trace 140, shown in
As described herein, the removal of the filler material 700 may form the cavity 120 defined by the substrate 100. In this example, the dielectric material 102 is coupled to the filler material 700A (shown in
The lateral trace 140 facilitates interconnection with the electrical components 210 (shown in
As previously described herein, the substrate 100 may include the lateral trace 140. The substrate 100 may define the cavity 120, and the lateral trace 140 may extend into cavity 120. The electrical component 210 (e.g., a die, a resistor, a capacitor, a transistor, or the like) may be positioned in the cavity and coupled with the lateral trace 140. The lateral trace 140 may facilitate the electrical communication of the electrical component 210 with the substrate 100.
The electronic device 1200 includes one or more electrical communication pathways between the substrate 100 and the POP substrate 1210. As described herein, the via 1220 may be coupled to the POP substrate 1210. In another example, the electrical component 210 is a semiconductor die (e.g., a through-silicon via die). The electrical component 210 may include interconnects 1230 on a plurality of sides of the component 210. For instance, a first interconnect 1230A may be positioned on a first side of the electrical component 210, and a second interconnect 1230B may be included on a second side of the electrical component 210. The interconnects 1230 may be exposed on a surface of the substrate 100. The POP substrate 1210 may be coupled to the electrical component 210. An electrical signal may be transmitted from the lateral trace 140, through the electrical component 1230, and to the POP substrate 1210.
