Title: Manufacture of semiconductor device
Inventor: NOMURA MASAAKI
IPC: H01L27/04
Filed: 1987-10-07
Abstract: PURPOSE:To realize a high resistance value of a high resistive load by a method wherein a polycrystalline silicon film is formed to be thin in order to realize the high resistance value of the high resistive load and the polycrystalline film is made selectively to be a refractory metal silicide by using a silicon oxide film as a mask in order to form a low-resistance wiring part. CONSTITUTION:An insulating film 2, a polycrystalline silicon film 3 and a silicon oxide film 4 are formed one after another on a substrate 1. Then, the silicon oxide film 4 is etched selectively; a refractory metal film 6 is formed at its opening. Then, a heat treatment operation is executed in a high-temperature atmosphere of a inert gas; a refractory metal silicide 7 is formed; in succession, the non-reacted refractory metal film is etched selectively; after that, the silicon oxide film 4 is then etched selectively. During this process, because a film to be made a silicide is thin, an etching operation hardly progresses in a transverse direction; it is possible to almost neglect a decrease in a resistance value at a high resistive load part due to extension in the transverse direction of a low resistance wiring part. By this setup, it is possible to further increase the resistance value of the high resistive load.
