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.

    摘要: Consistent with an example embodiment, a reduced surface field effect type (RESURF) semiconductor device is manufactured having a drift region over a drain region. Trenches are formed through openings in mask. A trench insulating layer is deposited on the sidewalls and base of the trenches followed by an overetching step to remove the trench insulating layer from the base of the trenches as well as the top of the sidewalls of the trenches adjacent to the first major surface leaving exposed silicon at the top of the sidewalls of the trench and the base of the trenches. Silicon is selectively grown plugging the trenches with silicon plug (18) leaving void.
