SELF-ALIGNED GATE STRUCTURE

This abstract first appeared for US patent application 18783955 titled 'SELF-ALIGNED GATE STRUCTURE

Original Abstract Submitted

The present disclosure generally relates to semiconductor processing for a self-aligned gate structure and corresponding semiconductor device. In an example, a semiconductor device includes a semiconductor substrate, a semiconductor gate layer, an offset dielectric layer, and a gate metal contact. The semiconductor gate layer is over the semiconductor substrate. The offset dielectric layer is over the semiconductor gate layer. The gate metal contact is over the offset dielectric layer and is through an opening through the offset dielectric layer. The gate metal contact contacts the semiconductor gate layer through the opening through the offset dielectric layer. A first sidewall of the semiconductor gate layer, a second sidewall of the offset dielectric layer, and a third sidewall of the gate metal contact are vertically aligned over the semiconductor substrate.
