Patent GB-1413371-A (GB)
Title: Integrated circuit
IPC: H03K19/00
Filed: 1973-01-05
Abstract: 1413371 Integrated circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Jan 1973 [8 Jan 1972] 735/73 Heading H1K [Also in Division H3] Operating current is supplied to circuit elements of a monolithic integrated structure by means of a rectifying bridge incorporated in the monolith and comprising, in adjacent arms, a pair of elements functioning as rectifiers connected between supply terminals and the substrate of the monolith, and in the other bridge arms PN junctions which inject minority carriers into the substrate for opposite supply voltage polarities respectively, which carriers are collected by a floating zone from which they are reinjected to provide operating current for the circuit elements. In the Fig. 1 arrangement the pair of rectifiers are constituted by the emitter junctions of a double emitter shortedcollector vertical transistor and the minority carriers injected into an N-type substrate layer epitaxially formed on an N + wafer from emitter zones 9, 10, respectively, of lateral transistors having a common floating collector zone 11 from which carriers are reinjected to supply base current to closely adjacent transistors such as inverted vertical transistors T4, T5. Zone 11 may be metallized to reduce its lateral resistance. The pair of rectifiers may alternatively be constituted by the emitter collector paths of transistors the bases of which are connected via resistances to the opposite supply terminals to their emitters. In a typical structure of this type, Fig. 5, the base zones 27, 28 of these transistors are elongated to provide the resistors, their extremities, which are interdigitated with collector zone 11, constituting the emitters of the lateral transistor structures. Fingers 37 may be truncated to reduce loss current resulting from collection of injected current by base zone 27, 28 without impairing the collection efficiency of zone 11. Further reduction can be achieved in the Fig. 6 structure, in which emitter zones 41, 42 are elongated to constitute the resistors by spacing base zones 27, 28 so far from zone 11 that they do not collect injected current and/or by providing an intermediate P zone shorted to the substrate. Efficiency is greatly increased ny surrounding the combination of zone 11 and zones to which it supplies current by an N+ doped zone which may extend down to the wafer. If, in the above structures the N + wafer is replaced by one of P type, providing the epitaxial layer is sufficiently thin the zone 11 can be dispensed with and its role played by the wafer itself.
