Method of manufacturing semiconductor device, method of forming pattern film, and metal-containing organic film
According to one embodiment, a method of manufacturing a semiconductor device is disclosed. The method of manufacturing a semiconductor device, includes forming an organic film containing polyacrylonitrile on a target film on a semiconductor substrate; applying a metal compound to the organic film to form a composite film; removing the composite film partially to form a pattern; heating the pattern-formed composite film; and processing the target film by using the heated composite film as a mask.
