Abstract:
A method of manufacturing a semiconductor device includes providing a semiconductor substrate including a main surface, the main surface including a first area and a second area, which is different from the first area in a plan view, forming a first trench in the main surface of the semiconductor substrate in the first area, after the forming the first trench, forming a first insulating film on a side wall surface and a bottom face of the first trench, and after the forming the first insulating film, forming a first conductor film over the semiconductor substrate in the first area and a second area to embed a portion of the first conductor film into the first trench through the first insulating film.

Claim (Index 1):
A method of manufacturing a semiconductor device, the method comprising:\n (a) providing a semiconductor substrate including a main surface, the main surface including a first area and a second area, which is different from the first area in a plan view; (b) forming a first trench in the main surface of the semiconductor substrate in the first area; (c) after the (b), forming a first insulating film on a side wall surface and a bottom face of the first trench; (d) after the (c), forming a first conductor film over the semiconductor substrate in the first area and the second area to embed a portion of the first conductor film into the first trench through the first insulating film; (e) after the (d), patterning the first conductor film to remain a first part of the first conductor film as an upper electrode of a capacitor element in the first area and to remain a second part of the first conductor film as a dummy gate electrode of a Metal Insulator Semiconductor Field Effect Transistor (MISFET) in the second area, the capacitor element including the first part with a portion embedded in the first trench, the first insulating film, and a part of the semiconductor substrate in the first area; and (f) after the (e), replacing the second part of the first conductor film with a metal material to form a metal gate electrode of the MISFET.
