Abstract: Five new methods for the formation of an improved liquid-crystal-on-silicon display are described, in which the device structure is enhanced by the photolithographic building of alignment posts among the mirror pixels of the micro-display. These five methods accommodate the fabrication of an optical interference multilayer, which improves the image quality of the reflected light. These five methods are: Silicon Dioxide Posts by Wet Etching. Amorphous Silicon Posts by Plasma Etching. Silicon Nitride Posts by Plug Filling. Insulation Material Posts by Lift-off. Polyimide Posts by Photosensitive Etching.

Abstract: A new method and apparatus for detecting and measuring the level of metal present on the surface of a substrate is achieved. Energy, in the form of rf or light or microwave energy, is directed at the surface of a wafer, the reflected energy or the energy that passes through the semiconductor substrate is captured and analyzed for energy level and/or frequency content. Based on this analysis conclusions can be drawn regarding presence and type of metal on the surface of the wafer. Furthermore, by inclusion of metal within the resonating circuit of an rf generator changes the frequency of the vibration and therefore detects the presence of metal.

Abstract: In the present invention a high performance package is described where semiconductor chips are stacked together in a pancake like fashion with inter chip communications facilitated by chip to chip vias formed through the material of each chip. The chip to chip vias are created by etching and filling a hole from the back of a chip through the silicon substrate stopping at the first level of metalization and invoking the wiring of the chip to complete the path to the top side. The chip in the stack are aligned so that chip to chip vias form columns. Signal and power can travel the full length of a column from the bottom chip to the chip on top, or the wiring within the chips can interrupt the signal flow and form interstitial connections. Interstitial connections can also be used to enhance the wireability between chips in the stack. To accommodate cooling the chips in the stack are made in varying sizes and are ordered in size from the largest at the bottom of the stack to the smallest at the top of the stack.

Abstract: An EEPROM MOSFET memory device with a floating gate and control gate stack above source and drain regions formed in a substrate self-aligned with the stack. There is a means for writing data to the floating gate electrode by applying an upwardly stepwise increasing control gate voltage V.sub.CG1 waveform applied to the control gate of the EEPROM device. The waveform is a voltage ramp providing a substantially constant tunneling current into the floating gate electrode which is approximately constant with respect to time so programming speed and the number of write/erase cycles is increased. The means for threshold voltage testing compares the voltage of the drain electrode to a reference potential.

Abstract: A process is described for generating, through ion implantation, any desired concentration profile. This is accomplished by providing a set of mono-energetic doping concentration profiles which, when superimposed, generate the desired concentration profile (in a manner analogous to generating a square wave by superimposing multiple sine waves). The ion current, accelerating voltage, and dose needed to generate each member of the set is then computed and fed as input to software that controls the operation of the implanter. The various profiles from the set are then implemented while the ion beam remains stationary, thereby generating the desired profile at that spot. The beam is then moved to the next intended location and the process is repeated. In an alternative embodiment, each profile in the set is implemented over the entire surface scanned by the beam and then the process is successively repeated for the remaining members of the set.
