Abstract: A single polycrystalline silicon configuration for a memory cell in a static MOS RAM and a method of fabricating the same are described. Three conductivity regions are utilized to form each memory cell. A first conductivity region is formed in the substrate to create a buried ground line and sources and drains of transistors. A second conductivity region is formed within an insulation layer and above the first conductivity region to create a word line, gate regions of the transistors, load resistors, and a power supply line. The power supply line is oriented directly above and parallel to the ground line. A third conductivity region is formed on the surface of the insulation layer to create data lines. The number of process steps and the size of the memory cell are reduced by this configuration.

Abstract: A method for producing an NPN semiconductor device which has a titanium-tungsten barrier metal only in the N type contact windows is disclosed. A semiconductor wafer first undergoes the washed emitter process with the result that the N type collector and emitter contact windows are exposed to bare silicon and the P type contact windows are covered by a layer of silicon dioxide. A layer of titanium-tungsten alloy is deposited on the surface of the wafer. The titanium-tungsten layer is etched out of the P type contact regions using standard photolithographic techniques. The underlying layer of silicon dioxide in the P type contact regions is then also etched away. A layer of aluminum is then deposited across the surface of the wafer. The conductor interconnect photolithography is used to etch away all undesired aluminum. The remaining portions of the titanium-tungsten layer, not covered by aluminum signal lines, are then also etched away.
