IPC: G06F9/48
Filed: 1990-04-11
Abstract: PURPOSE:To maintain the real time property without losing the uniformity of each time even when it is desired to process preferentially a specific task by executing each task by setting arbitrarily a ratio of the number of times of execution of its instruction at every task of (n) pieces processed in parallel. CONSTITUTION:The arithmetic processor is constituted of a wait flag circuit 1, a swap control circuit 2, and counters 3 - 6.

Abstract: PURPOSE:To stably form a metal silicide film on a gate electrode region or the like, by a method wherein, after a polycrystalline silicon deposition film is formed on the substrate surface containing a silicide film, heat treatment is performed, and unreacted polycrystalline silicon is selectively eliminated by wet-etching using etching solution whose main component is hydrazine. CONSTITUTION:A titanium silicide film 8 is formed on the surfaces of a gate electrode region 4 and a source/drain region 5. A deposition film 9 composed of polycrystalline silicon is formed on the whole surface of a substrate 1 containing the titanium silicide film 8. By performing heat treatment, reaction is generated between the polycrystalline silicon film 9 and the metal silicide film 8, which is subjected to phase inversion to low resistance composition. Further after the heat treatment, wet etching is performed by using etching solution whose main component is hydrazine, and unreacted polycrystalline silicon is eliminated. Hence only the polycrystalline silicon film 9 is completely eliminated without etching the titanium silicide film 8.
