    摘要： Semiconductor devices and methods for making semiconductor devices. The present invention allows a flip chip assembly to be used with an optical semiconductor device. The optical semiconductor flip chip is positioned over a hole in a PCB such that the imaging area of the optical semiconductor flip chip faces the hole. The hole allows the imaging area to be unobstructed by the PCB. Underfill material can be prevented from going into the hole by erecting a barrier on top of the PCB that surrounds the hole.

    摘要： The invention provides a packaging technique implementing an electronic circuit, comprising several individually packaged sub-circuits, on a circuit board within the footprint of a single package. The embodiment of the present invention is particularly advantageous when implementing application specific integrated circuits (ASICs) or field programmable gate arrays (FPGAs). Selected pins of an upper package are electrically coupled to corresponding pins of the next lower adjacent package such that the pins of the uppermost package can be coupled to the pins of the lowermost package and correspondingly to the signal leads and power bus conductors of the printed circuit board. Portions of selected pins may be removed from one or more packages prior to forming the stacked structure to electrically isolate corresponding pins of upper packages from the pins of lower packages. A template is provided that permits rapid identification of pins to be removed before the packages are configured in the stack.Careful partitioning of the electrical circuit permits a limited number of standard bonding patterns to be combined in a large variety of configurations by rotating packages relative to adjacent packages in the stack. Each package is also provided with additional pins that may be used for vertical routing in a manner that couples non-adjacent packages without coupling to intervening packages. Heat sinks and heat pipes are attachable to the stack to increase thermal dissipation.

    摘要： A low-stress silicon-backed light valve package assembly that includes a matched coefficient of thermal expansion (CTE) substrate with a CTE no greater than 300% of the CTE of silicon, a silicon-backed light valve adhered to the matched CTE substrate by a soft adhesive layer, a flexible circuit adhered to the matched CTE substrate and electrically connected to the silicon-backed light valve, an encapsulant dam surrounding the silicon-backed light valve and a soft encapsulant layer filling the cavity defined by the encapsulant dam. Both the soft encapsulant layer and the soft adhesive layer have a Shore A hardness of less than 5. The combination of a soft encapsulant layer, soft adhesive layer and matched CTE substrate insure sufficiently low mechanical stress levels to avoid the presence of optical interference patterns in the light valve display.
