Abstract

1502122 Semi-conductor devices RCA CORPORATION 12 Aug 1975 [19 Aug 1974] 33548/75 Heading H1K A semi-conductor device, particularly a high power device in integrated form, comprising two transistors 14, 18 with their collector regions 26, 28 and 60, 62 respectively, electrically connected together, is characterized in that the transistor 18 has its common emitter current gain less than that of the conventional transistor by at least an order of magnitude, and in particular lying between 0À05 and 0À25, so that the transistor 18 functions as a diode 16 having its base and emitter regions 58, 56 and 54 respectively, virtually isolated from the collector electrode 40 of the transistor 14, the device being further characterized in that each transistor is provided with a first base region partly surrounding its emitter region, and a common second base region 58 of the same conductivity type as the first base region but of lower conductivity type and laterally surrounding the respective first base region. The low value of the common emitter current gain is obtained by (1) providing a shallow emitter region 54 of, e.g. depth 0À1 mil. as compared to 0À7 mil. depth of the emitter region 20, Fig. 1, or (2) by providing a base (86), Fig. 3 (not shown), of a transistor (88) with a deeper region than that of the P+ base (22<SP>1</SP>) of a transistor 141, the depths of the emitter regions (20<SP>1</SP>, 84<SP>1</SP>) being the same in both the transistors. The impurity distribution profiles in the embodiment of Fig. 1 in the base and collector regions of both the transistors are substantially identical along vertical lines that do not intersect the emitter regions, whereas in the embodiment of Fig. 3, impurity distribution profiles in the emitter and collector regions are substantially identical.
