    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.

The bipolar transistor is provided with a first insulating cavity (92) provided in the collector region (22d and 22e). The base region (33d) is narrower in the plane of the substrate than the collector region (22d and 22e) due to a second insulating cavity (94) provided around the base region (33d) and between the collector region (22d and 22e) and the emitter region (4). By blocking diffusion from the base region the first insulating cavity (92) provides a reduction in the base collector capacitance and can be described as defining the base contact.

    摘要: The invention relates to a semiconductor device (10) with a substrate (11) and a semiconductor body (12) of silicon which comprises an active region (A) with a transistor (T) and a passive region (P) surrounding the active region (A) and which is provided with a buried conducting region (1) of a metallic material that is connected to a conductive region (2) of a metallic material sunken from the surface of the semiconductor body (12), by which the buried conductive region (1) is made electrically connectable at the surface of the semiconductor body (12). According to the invention, the buried conducting region (1) is made at the location of the active region (A) of the semiconductor body (12). In this way, a very low buried resistance can be locally created in the active region (A) in the semiconductor body (12), using a metallic material that has completely different crystallographic properties from the surrounding silicon. This is made possible by using a method according to the invention. Such a buried low resistance offers substantial advantages both for a bipolar transistor and for a MOS transistor.
