Classification: CPC H | IPC H

Claim 3:
4. A semiconductor device comprising:
a semiconductor body;
a first gate structure disposed over the semiconductor body in a first region of the semiconductor body;
a first silicide region disposed proximate the first gate structure in the first region;
a second gate structure disposed over the semiconductor body in a second region of the semiconductor body, the second region contacting the first region;
an oxide layer disposed over the second gate structure and extending toward the first gate structure to an edge between the first region and the second region; and
a silicon nitride region disposed, at the edge, over a portion of the oxide layer, wherein the silicon nitride region occupies a surface area of less than 50% of a total surface area of the semiconductor body.
