Abstract

1531735 Integrated circuits SIEMENS AG 11 Sept 1975 [30 Sept 1974] 37352/75 Heading H1K A bipolar logic circuit comprises, in an epitaxial layer 4 on a semi-conductor substrate, a lateral bipolar transistor 1, a collector region 15 of which also constitutes the base region of an inwardly-operated vertical bipolar transistor 2. The epitaxial layer 4 itself constitutes the base 12 of the lateral transistor 1 and the emitter 23 of the vertical transistor 2, and is preferably earthed, the emitter region 11 of the lateral transistor 1 being connected to a voltage supply line. The vertical transistor 2 has at least two collector regions 21, 22 which provide the outputs from the circuit. The lateral transistor 1 has, in addition to the "output" collector 15, two "control" collectors 13, 14 located between the collector 15 and the emitter 11 and forming the circuit inputs. If a buried layer is present below the epitaxial layer 4 the regions 11, 13, 14 and 15 do not extend down to nest it. Two preferably earthed auxiliary collector regions 6 alongside the transistors 1, 2 serve to withdraw excess charge carriers. In a modification (Figs. 3 and 4, not shown) the collectors 14, 15 of the lateral transistor are combined as a single region. In a further modification of the Fig. 2 embodiment the collector 13 may be omitted and replaced by a further collector alongside the collector 14.
