Patent ID: 11876096
Assignee: SANDISK TECHNOLOGIES, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. The semiconductor structure of claim 1, wherein each of the gate electrodes comprises:
a semiconductor gate electrode portion contacting a top surface of a respective one of the gate dielectrics; and
a metallic gate electrode portion that overlies the semiconductor gate electrode portion and having a first length along a second horizontal direction that is perpendicular to the first horizontal direction,
wherein the semiconductor gate electrode portion comprises an upper region having the first length and a lower region having a second length along the second horizontal direction that that is greater than the first length, and
the first length of the metallic gate electrode portion along the second horizontal direction is smaller than a length of the active region in the second horizontal direction, such that an edge of the metallic gate electrode portion which extends along the first horizontal direction is located over the active region.
