Abstract: A high performance integrated circuit chip package includes a support substrate having conductors extending from one face to the opposite face thereof and a multilayer wiring substrate on the opposite face of the support substrate for connecting chips mounted thereon to one another and to the conductors. A heat sink includes microchannels at one face thereof, with thermally conductive cushions connecting the one face of the heat sink with the exposed back sides of the chips, to provide a high density chip package with high heat dissipation. The support substrate and heat sink may be formed of blocks of material having thermal expansion matching silicon. The cushions are a low melting point solder, preferably pure indium, and are sufficiently thick to absorb thermal stresses, but sufficiently thin to efficiently conduct heat from the chips to the heat sink.

Abstract: The invention is an improvement in a liquid crystal display device of the type having spaced front and rear glass panels, a transparent electrode layer, and an array of individually addressable pel electrodes separated from the transparent electrode layer by a cavity filled with liquid crystal material. The improvement comprises a color filter layer in the form of a decal pattern. The decal pattern is formed using interference film techniques which form an inorganic color filter. The decal is placed on one of the glass panels using known decal transfer methods. The inorganic nature of the color filter layer and the decal transfer methods allow for enhanced optical density of the color liquid crystal display.

Abstract: Decal technology is employed to provide a color filter layer for a thin film transistor liquid crystal display device. The red/green/blue color regions and an opaque surround are printed on a suitable substrate using gravure printing techniques and colored glass frit materials. Once the printed decal is transferred to one of the glass panels, it can be heated to fuse it to the glass. Electrodes can be deposited directly on this fused color filter layer.

Abstract: The color filters required for a thin film transistor liquid crystal display device are provided by using polychromatic glass for either the front or rear glass panel of the device. Through a series of masking, ultraviolet exposure and heat treating steps, red, green, and blue color areas can be generated in the polychromatic glass. Each of the different colored areas is, of course, to be aligned with one of the individually-addressable pel electrodes in the device. Two embodiments are described. In the first, the polychromatic glass forms the rear glass panel of the device and serves as a substrate for the thin film transistors used to individually address pel electrodes. In an alternate embodiment, the front glass panel of device is treated to form the color filter regions.
