Patent ID: 11923446
Assignee: GLOBALFOUNDRIES U.S. INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. A method of forming a semiconductor device comprising:
forming an active region above a substrate, the active region comprising a channel layer and a barrier layer formed on the channel layer;
forming an isolation layer above the substrate, the isolation layer being adjacent to the channel layer;
forming source and drain electrodes to contact the active region;
forming a gate above the active region, the gate is laterally between the source and drain electrodes, the gate has an upper surface;
forming a polysilicon layer above the substrate, the polysilicon layer has a lower surface, wherein the polysilicon layer is formed above the isolation layer, and wherein the polysilicon layer is positioned laterally adjacent to the gate and the lower surface of the polysilicon layer is at a lower elevation than the upper surface of the gate; and
forming a silicide layer on the polysilicon layer.
