Abstract

1275848 Semi-conductor devices ITT INDUSTRIES Inc 24 Sept 1970 [29 Sept 1969] 45508/70 Heading H1K In order to provide a transistor structure with a particularly flat large-signal current gain characteristic for a wide range of collector current values a lateral bipolar transistor is provided in the same semi-conductor body as, and in parallel with, a normal bipolar transistor in which base current flows perpendicularly to the major device surface. The normal transistor may be hometaxial or planar, having, in the latter case, diffused N-type and P-type emitter and base regions 3, 1 in an N-type Si body 4<SP>1</SP>, which may be homogeneous or may include an epitaxial layer. The lateral transistor then comprises an emitter region 3 and collector region 4, the three regions thereof being continuous with those of the normal transistor. The regions of the lateral transistor surround those of the normal transistor, the emitter region of which may be diffused through a meandering or combshaped masking layer 2<SP>1</SP>. Corresponding regions of the two transistors may, instead of being continuous with one another, be connected by conductors.
