Abstract: PURPOSE:To obtain the structure of a cross section having few step parts, by depositing a polycrystalline silicon layer, forming an oxide film in a region, where a high resistance body is to be formed, depositing a silicide film, and the like, thereby making it possible to form a low resistance body and a high resistance body using one-layer polycrystalline silicon layer or polycide layer. CONSTITUTION:A diffused region is selectively formed in a semiconductor substrate 1. A polycrystalline silicon layer is deposited through a gate oxide film 3 and a field oxide film 2. An oxide film 5 is formed on a region, where a high resistance body is formed, in the polycrystalline silicon layer 24. Silicide layers 7' and 7 are deposited on the oxide film 5 and said polycrystalline silicon layer 4. By said oxide film 5, the silicide film 7 on the polycrystalline silicon layer 4 is isolated from the silicide film 7' on the oxide film 5. Thereafter, e.g., the resistance of a polycrystalline silicon layer 4' is made low by phosphorus ion implantation from the upper part of the silicide film 7 and the like. In order to form a gate electrode and a wiring region, the silicide film 7' on the oxide film 5 and the polycrystalline silicon layer and the silicide film at the unnecessary parts are removed.
