Abstract

PURPOSE:To enable to obtain a polycrystalline Si resistor of a semiconductor device having high sheet resistance with high precision by a method wherein the whole of the lower face of the polycrystalline Si resistor is made to come in contact with the upper face of an oxide film formed on an Si substrate. CONSTITUTION:The SiO2 film 42 is formed on the Si substrate 43, and the polycrystalline Si film 41 is formed on the film 42 thereof. Moreover an SiO2 film 44 is formed coming in contact with the upper face and the sides of the film 41, and an SiO2 film containing impurity of B, P, etc., is formed on the film 44. The film 41 is covered with the film 44 by this way before etching of a gate oxide film, etc., is to be performed, and after then, when etching of the gate oxide film, etc., is performed reserving the part of the film 41, because the part of the film 41 is not etched, structure wherein the whole of the lower face of the film 41 is coming in contact with the SiO2 film of one kind can be obtained. The film 44 formed on structure having no rip by this way has the faculty being sufficient as a protective film, and even when an SiO2 film containing B or P is formed thereon and heat treatment is performed, the resistance value of the film 41 is not affected.
