Abstract

A part of the semiconductor substrate is processed to form fins protruding from the upper surface of the semiconductor substrate. Next, an interlayer insulating film is formed on the semiconductor substrate including the fin FA, and an opening is formed in the interlayer insulating film. Next, a dummy pattern including the dummy material and the insulating film is formed in the opening in a self-aligned manner. Thereafter, the dummy pattern is replaced with a memory gate electrode, a control gate electrode, and the like.
