Abstract:
A semiconductor device includes a semiconductor substrate, an isolation structure; a first gate dielectric layer and a first gate electrode. The isolation structure is formed in the semiconductor substrate to divide the semiconductor substrate at least into a first active region and a second active region. The first gate dielectric layer is disposed on the first active region, and has a plane top surface contacting to a sidewall of the isolation structure and forming an acute angle therewith. The first gate electrode stacked on the plane top surface.

Claim (Index 6):
A method for fabricating a semiconductor device comprising:\n providing a semiconductor substrate; forming a first gate dielectric layer, a protection layer and a hard mask layer in sequence on the semiconductor substrate; forming an isolation structure in the semiconductor substrate and passing through the first gate dielectric layer, the protection layer and the hard mask layer, so as to at least divide the semiconductor substrate into a first active region and a second active region; removing the hard mask layer, the protection layer and a portion of the first gate dielectric layer disposed on the second active region; and forming a first gate electrode on a remaining portion of the gate dielectric layer disposed on the first active region.
