Patent ID: 7435682

Claim:
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 intermediate 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, the first organic film comprising a novolac resin and being subjected, in formation thereof, to a baking of not lower than a crosslinking-finishing temperature thereof; 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, the polishing being performed using a slurry containing γ-alumina as abrasive particles; and forming a second organic film above the insulating film and above the first organic film; and subjecting the resist film to patterning exposure.
