Title: Manufacture of semiconductor device
Inventor: KOBAYASHI YASUTAKA
IPC: H01L21/8234
Filed: 1990-09-05
Abstract: PURPOSE:To enable transistor in various kinds of structures to be formed within a same device by using a same type of material as a gate electrode for a gate electrode side wall and by using it as a one-piece gate material assimilating with a spacer or the gate electrode. CONSTITUTION:A photoresist 15 is subjected to patterning for a lightly doped drain(LDD) part and an As single drain part and a double diffused drain(DDD) part are covered with the resist 15 entirely. An oxide film 17 is formed, the photoresist 15 is eliminated, and a polysilicon film 18 which is made of a same material as a gate electrode 14a is formed on the entire surface. Then, the film 18 is etched and a side wall 19 is formed on a side wall of the electrode 14a as a spacer. A side wall 19 which acts as a mask when forming source/drain at the LDD part becomes one part of a gate electrode 14b in As single drain structure and DDD structure, thus enabling a transistor in the LDD structure, As single drain, or DDD structure to be formed selectively at any part within the same device.
