Abstract:
Fabrication methods and device structures for a heterojunction bipolar transistor. A trench isolation region is formed that surrounds an active region of semiconductor material, a collector is formed in the active region, and a base layer is deposited that includes a first section over the trench isolation region, a second section over the active region, and a third section over the active region that connects the first section and the second section. An emitter is arranged over the second section of the base layer, and an extrinsic base layer is arranged over the first section of the base layer and the third section of the base layer. The extrinsic base layer includes a first section containing polycrystalline semiconductor material and a second section containing single-crystal semiconductor material. The first and second sections of the extrinsic base layer intersect along an interface that extends over the trench isolation region.

Claim (Index 6):
The structure of  claim 1  wherein the trench isolation region includes a top surface that is coplanar with the top surface of the active region, and the interface is inclined at an angle of less than 90\u00b0 relative to the top surface of the trench isolation region.
