Abstract

1392381 Integrated circuits SIEMENS AG 16 May 1972 [11 June 1971] 22845/72 Heading H1K [Also in Division H3] In Fig. 4 a photo-transistor having an emitter 16, a base 15 and a collector 14 is connected in series with a load transistor comprising an emitter 14, a base 15 and a collector 22 by sharing the common region 14. Likewise in Fig. 5 a common region 14 serves as and interconnects the base region of a lateral transistor 30, 24, 31 and the collector region of a transistor 24, 25, 26.
