IPC: H01L21/3205
Filed: 1987-12-29
Abstract: PURPOSE:To make a microscopic and high-integration semiconductor device by a method wherein a tungsten film deposited on a semiconductor substrate is heat-treated in an atmosphere of nitrogen at a high temperature in order to reduce an oxygen concentration value in said film and, when the tungsten film is to be etched by an RIE method using a fluorine-based reaction gas, in order to reduce the etching shift amount. CONSTITUTION:A gate SiO2 film 2 is formed, e.g., on an n-type or p-type semiconductor substrate 1; a tungsten film 3 is deposited. During this process, residual oxygen contained inside a sputtering apparatus is absorbed into the tungsten film 3. Then, in order to form an SiN film 6 for a blocking material, this assembly is heat-treated at a high temperature of 760 deg.C in a mixed gas of SiH4 and NH3. By this setup, oxygen in the tungsten film 3 is released; an oxygen concentration value in the film 3 is reduced. After that, in order to form a gate electrode, a resist film 4 is applied and patterned, and is etched in a reaction gas of SF6 by an RIE method; because the oxygen concentration value in the film 3 has been reduced, dissociation of a fluorine atom is suppressed, an etching rate is reduced; side etch is hardly caused; the etching shift amount can be reduced extremely.
