748,925. Transistors. WESTERN ELECTRIC CO., Inc. Nov. 25, 1953 [Dec. 16, 1952] No. 32720/53. Class 37. A signal translating device comprises a semi. conductor body having a substantially intrinsic region contiguous with an extrinsic region, a collector connection to the intrinsic region, and emitter and base connections to the extrinsic region. The arrangement provides low base resistance and low connector capacitance. In Fig. 1 a wafer 10 of silicon or germanium has an intrinsic zone 11, and a strong N-type zone 12 bearing the base contact and in contact with a P-type portion 13 constituting part of the emitter connections. The collector connection is provided by a P-type portion 14 which contacts the intrinsic region 11. The emitter is biased positively and the collector has only a small negative bias. The emitter and/or collector contact may be constituted by a point contact instead of a P-type region. Specifications 700,231, 706,858 and 724,930 are referred to.
