Abstract:
Techniques for fabricating a semiconductor device having a two-part spacer. In one embodiment, a device is provided that comprises a spacer having a first portion and a second portion, where the first portion comprises one or more layers and the second portion comprises a dielectric material. In one or more implementations, the device further comprises an isolation layer coupled to the spacer, where the isolation layer comprises a silicon oxide material. In one or implementation, the device can further comprise a gate structure formed on a substrate, where the gate structure comprises a polysilicon contact portion, a first silicon dioxide portion, a silicon nitride portion and a second silicon dioxide portion.

Claim (Index 9):
A method, comprising:\n forming a spacer having a first portion and a second portion, wherein the first portion comprises one or more layers and the second portion comprises a dielectric material; forming an isolation layer coupled to the spacer on a first side of the isolation layer, wherein the isolation layer comprises a silicon oxide material; forming a drain structure coupled to a second side of the isolation layer, wherein the second side of the isolation layer is opposite the first side of the isolation layer, wherein the spacer, the isolation layer and the drain structure comprise a gate structure; providing the gate structure on a substrate; forming an etch stop layer on the isolation layer and around the gate structure; and forming a dummy layer over the etch stop layer, and forming a spacer layer over the dummy layer and around an exposed portion of the gate structure, wherein the spacer layer is distinct from the spacer.
