Abstract

PURPOSE:To provide a layer to reduce the carrier injection from the emitter on the emitter/base conjuction surface except the specified area immediately under the collector region, thus obtaining a I<2>L of which effective emitter/base conjunction and which has an improved inverter current amplifying ratio and greater shield frequency to ensure high speed operation.
