  • Patent number: 8901733
    Abstract: In accordance with the objectives of the invention a new method is provided for the creation of metal bumps over surfaces of I/O pads. Contact pads are provided over the surface of a layer of dielectric. The aluminum of the I/O pads, which have been used as I/O pads during wafer level semiconductor device testing, is completely or partially removed over a surface area that is smaller than the surface area of the contact pad using methods of metal dry etching or wet etching. The contact pad can be accessed either by interconnect metal created in a plane of the contact pad or by via that are provided through the layer of dielectric over which the contact pad has been deposited. The process can be further extended by the deposition, patterning and etching of a layer of polyimide over the layer of passivation that serves to protect the contact pad.

  • Patent number: 8748227
    Abstract: A Chip Scale Package (CSP) and a method of forming the same are disclosed. Single chips without the conventional ball mountings, are first attached to an adhesive-substrate (adsubstrate) composite having openings that correspond to the input/output (I/O) pads on the single chips to form a composite chip package. Ball mounting is then performed over the openings, thus connecting the I/O pads at the chip sites to the next level of packaging directly. In another embodiment, the adhesive layer is formed on the wafer side first to form an adwafer, which is then die sawed in CSPs. Then the CSPs with the adhesive already on them are bonded to a substrate. The composite chip package may optionally be encapsulated with a molding material. The CSPs provide integrated and shorter chip connections especially suited for high frequency circuit applications, and can leverage the currently existing test infrastructure.

  • Publication number: 20140082926
    Abstract: Embodiments described herein take the form of fixtures to be used in a manufacturing process. In particular, a manufacturing fixture may be sized to accept one or more electronic components, such as a printed circuit board (PCB) having various electrical elements. The PCB may be placed on the fixture in a predetermined area. The PCB may be placed in a depression or aperture sized to accept the PCB. When the PCB is placed within the fixture, a cover may be lowered or otherwise placed across the PCB in order to hold the PCB in place. The cover contacts the PCB and is pliable or malleable to conform to those portions of the PCB it contacts. When the cover is closed, a negative pressure may be induced in the fixture beneath the cover. When the PCB is held in position, the manufacturing fixture may operate on the PCB.

  • Patent number: RE43674
    Abstract: A new post-passivation metal interconnect scheme is provided over the surface of a IC device that has been covered with a conventional layer of passivation. The metal scheme of the invention comprises, overlying a conventional layer of passivation, thick and wide metal lines in combination with thick layers of dielectric and bond pads. The interconnect system of the invention can be used for the distribution of power, ground, signal and clock lines from bond pads to circuits of a device that are provided in any location of the IC device without introducing significant power drop. No, or smaller ESD circuits are required due to the low impedance post-passivation interconnection, since any accumulated electrostatic discharge will be evenly distributed across all junction capacitance of the circuits on the chip. The post passivation metal scheme is connected to external circuits through bond pads, solder bonding, TAB bonding and the like.
