IPC: H01L21/8226
Filed: 1984-12-18
Abstract: PURPOSE:To improve the degree of integration and yield by connecting a level shift diode in the forward direction between an island region and ground potential. CONSTITUTION:Level shift diodes D1 are each biased in the forward direction among a base in a lateral PNP transistor Q1 using an island region 4 and an emitter in a reverse vertical type transistor QR and ground potential GND. An equivalent diode Dj functioning while using a P type diffusion region 6b as an anode and the island region 4 as a cathode and the level shift diode D1 are connected in series between a collector in the lateral PNP transistor Q1 at a final step employed as load for an output and ground potential GND. It means the application of a value twice as large as the forward rise voltage Vf of the diode as VBE of a linear transistor TR connected to the base from the collector in the lateral PNP transistor Q1. Accordingly, the linear transistor TR can be driven directly as load for an output from the lateral PNP transistor Q1 in an IIL.
