METHOD FOR MANUFACTURING SEMICONDUCTOR DEVICE

摘要

A method for manufacturing a semiconductor device includes a photolithography process having steps of a developing solution immersing process. The steps of the developing solution immersing process includes step (a) of dropping a developing solution on a silicon carbide semiconductor substrate and forming a developing solution film so as to have a film thickness of more than 6 μm and step (b) of reducing the film thickness of the developing solution film to 6 μm or less.
