US Patent 7435682 Method of manufacturing semiconductor device

Disclosed is a method of manufacturing a semiconductor device comprising forming an insulating film above a substrate, forming a recess in the insulating film, successively forming an underlying layer, an immediate layer and a resist film above the insulating film having the recess formed thereon, the underlying layer being formed by a process comprising forming a first organic film above the insulating film, chemically mechanically polishing the first organic film to expose a surface of the insulating film and to remain the first organic film selectively in the recess, and forming a second organic film above the insulating film and above the first organic film, and subjecting the resist film to patterning exposure.
