Title: Manufacture of semiconductor device
Inventor: OMOTO KAYOKO
IPC: H01L21/8234
Filed: 1987-07-02
Abstract: PURPOSE:To enable ion to be implanted without using resist as a mask simultaneously preventing a gate oxide film from breaking by a method wherein, after forming gates, an oxide film is formed on the whole surface of a chip in case of implanting N-type impurity. CONSTITUTION:Gates 4a, 4b are formed by resist patterns 5a. After removing the resist patterns 5a, oxide films 3a are formed on overall surface of a chip by thermal oxidation. Next, P-type impurity is implanted to form P-type diffused regions 6 using resist patterns 5b as masks. The oxide films 3a on N channel side are etched using resist pattern 5c as a mask. Later, the resist pattern 5c is removed and N type impurity is implanted to form N-type diffused regions 7. At this time, the oxide films 3a fill the role of the mask on P channel side. Thus, in case of implanting the P-type impurity, the gate oxide film on the N channel side can be prevented from breaking. Furthermore, the potential of polysilicon can be prevented from being boosted due to the oxide film 3a formed between gate polysilicons.
