Abstract:
A semiconductor device, comprising:a semiconductor substrate having a surface;an isolation region in the surface of the semiconductor substrate;an active region in the surface of the semiconductor substrate surrounded by the isolation region, the active region having a perimeter and including a main portion having a substantially straight main edge and an expanded portion attached to a part of the main edge of the main portion;a gate electrode including a main electrode portion, a contact portion and an inclined portion between the main electrode portion and the contact portion, the main electrode portion and the inclined portion being disposed at least partially over the main portion of the active region, the contact portion being disposed at least partially on the isolation region, the inclined portion having an edge and being inclined relative to the main electrode portion, the edge of the inclined portion of the gate electrode and a boundary between the main portion and the expanded portion of the active region making a first angle that is substantially less than 90.degree.,wherein the expanded portion of the active region increases a distance from the edge of the inclined portion of the gate electrode to the perimeter of the active region.
