    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.
