    摘要: Methods for manufacturing a bipolar transistor semiconductor device are described, along with devices fabricated in accordance with the methods. The methods include the steps of forming a stack of layers over a semiconductor body comprising a window definition layer (18,38), a layer (20) of semiconductor material, a first insulating layer (22), and a second insulating layer (24) which is selectively etchable with respect to the first insulating layer. A trench (26) is then etched into the stack down to the window definition layer. The portion of the trench extending through the second insulating layer is widened to form a wider trench portion (28) therethrough. A window (36) is defined in the window definition layer which is aligned with the wider trench portion, and serves to define the base-collector or base-emitter junction in the finished device.

    摘要: A semiconductor device (10) comprising a bipolar transistor and a field effect transistor within a semiconductor body (1) comprising a projecting mesa (5) within which are at least a portion of a collector region (22d and 22e) and a base region (33d) of the bipolar transistor. 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.
