Abstract:
According to an aspect of the present invention, there is provided a method for manufacturing a semiconductor device including: sequentially forming a first insulating film, a first electrode film, a second insulating film, and a second electrode film on a substrate; forming a groove that separates the second electrode film, the second insulating film and the first electrode film; forming an insulating film inside the groove so that an upper surface thereof is positioned between upper surfaces of the second electrode film and the second insulating film; forming an overhung portion on the second electrode film so as to overhang on the insulating film by performing a selective growth process; and forming a low resistance layer at the overhung portion and the second electrode film by performing an alloying process.
