Abstract:
1. A semiconductor device comprising: a semiconductor substrate, a plurality of active areas extending in one direction and protruding upward being formed at an upper surface of the semiconductor substrate; an element isolation insulator embedded in a lower portion of a trench between the active areas; an insulating block made of a first insulating material and disposed directly on the element isolation insulator, a lower portion of the insulating block being disposed in the trench, an upper portion of the insulating block protruding above an upper end of the active area; an interlayer insulating film made of a second insulating material different from the first insulating material and provided on an upper side of the semiconductor substrate and the insulating block; and a contact formed in the interlayer insulating film, a lower end of the contact being connected to an upper surface of the active area, a part of a lower surface of the contact located directly on the insulating block being positioned higher than a part of a lower surface of the contact located directly on the active area.
