Abstract
PURPOSE: To establish fine pattern with good yield rate even to thick insulation film, by providing the pattern of organic compound such as photo resist film on the semiconductor substrate and removing the pattern after coating the insulation film on it.
CONSTITUTION: The photo resist pattern 12 is placed on the semiconductor substrate 11, heat treatment of 180 to 400°C is made in inactive gas, and hardening is made with carbonization. Next, thich SiO2 film 13 is grown on the entire surface of the substrate 11 including the pattern 12 with CVD method, and the thickness of the film 13 grown at the upper and side surface of the pattern 12 is very thin with the progress of carbonization since the O2 enters in the pattern 12 at the reaction of SiH4 +O2 → SiO2 +2H2. Then, since pin holes are caused much, the removal of the pattern 12 is made easy by either of heated sulphuric acid or O2 plasma. establishing the fine pattern of desired SiO2 film 13. Thus, the diffusion region 16 and so on are formed.
