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

Claim 10:
11. A structure comprising:
an extrinsic base region vertically over an intrinsic base region comprising semiconductor on insulator substrate material;
a raised collector region on the semiconductor on insulator substrate material;
a raised emitter region on the semiconductor on insulator substrate material;
a first structure electrically isolating the extrinsic base region from the raised emitter region; and
a second structure electrically isolating the extrinsic base region from the raised collector region, the second structure being of a different composition than the first structure, wherein the first structure comprises a sidewall spacer and the second structure comprises a gate structure with asymmetrical sidewall spacers, the gate structure being electrically connected to the raised collector region and the sidewall spacer is different than one of the asymmetrical sidewall spacers between the gate structure and the extrinsic base region.
