摘要： A bipolar transistor is fabricated having a collector (52) in a substrate (1) and a base (57, 58) and an emitter (59) formed over the substrate. The base has a stack region (57) which is laterally separated from the emitter (59) by an electrically insulating spacer (71). The insulating spacer (71) has a width dimension at its top end at least as large as the width dimension at its bottom end and forms a Γ-shape or an oblique shape. The profile reduces the risk of silicide bridging at the top of the spacer in subsequent processing, while maintaining the width of emitter window.

摘要： A method of forming a heterojunction bipolar transistor by depositing a first stack comprising an polysilicon layer and a sacrificial layer on a mono-crystalline silicon substrate surface; patterning that stack to form a trench extending to the substrate; depositing a silicon layer over the resultant structure; depositing a silicon-germanium-carbon layer over the resultant structure; selectively removing the silicon-germanium-carbon layer from the sidewalls of the trench; depositing a boron-doped silicon-germanium-carbon layer over the resultant structure; depositing a further silicon-germanium-carbon layer over the resultant structure; depositing a boron-doped further silicon layer over the resultant structure; forming dielectric spacers on the trench sidewalls; filling the trench with emitter material; exposing polysilicon regions outside the trench side walls by selectively removing the sacrificial layer; implanting boron impurities into the exposed polysilicon regions to define base implants; and exposing the resultant structure to a thermal budget for annealing the boron impurities.
