    摘要: The present invention solves the problems present in the prior art by forming a lateral emitter base junction of a bipolar transistor in which an N+ polysilicon layer forms the emitter. This is accomplished by attaching the polysilicon emitter to a vertical surface of the single crystal silicon. Single crystal silicon (102) is grown on a dielectric (104) and covered with another dielectric layer and an extrinsic base polysilicon layer (106). Polysilicon sidewall spacers (112) are formed as an edge strap connection between the extrinsic base and the single crystal silicon. The edge strap is isolated from the remainder of the device by a second sidewall spacer (114). An intrinsic base region (150) is formed in the single crystal silicon using the sidewall spacer as one defining edge of the intrinsic base region. The intrinsic base region (150) diffuses under the sidewall spacers. The single crystal silicon is etched to the underlying dielectric using the second sidewall spacer as one defining edge. This etch removes all the intrinsic base region except that under the sidewall spacers and leaves a vertical surface of the single crystal silicon exposed. This exposed vertical surface is the intrinsic base region. Conformal N type polysilicon (125) is then deposited to form an emitter contact on the vertical surface of the single crystal silicon intrinsic base region.

    摘要: The invention relates to a semiconductor device (10) with a semiconductor body (12) comprising a bipolar transistor with an emitter region (1), a base region (2) and a collector region (3) of, respectively, a first conductivity type, a second conductivity type, opposite to the first conductivity type, and the first conductivity type, wherein, viewed in projection, the emitter region (1) is positioned above or below the base region (2), and the collector region (3) laterally borders the base region (2). According to the invention, the base region (2) comprises a highly doped sub­region (2A) the doping concentration of which has a delta-shaped profile in the thickness direction, and said highly doped sub-region (2A) extends laterally as far as the collector region (3). Such a lateral bipolar transistor has excellent high-frequency properties and a relatively high breakdown voltage between the base and collector regions (2, 3), implying that the device is suitable for high power applications. The doping concentration lies preferably between about 1019 and about 1020 at/cm3, and the thickness of the sub-region (2A) lies between 1 and 15 nm and preferably between 1 and 10 nm. The invention also comprises a method of manufacturing such a device (10).
