Integrated injection logic semiconductor devices

摘要

The integrated injection logic semiconductor device comprises an N type semiconductor substrate, a P type semiconductor layer laminated on the N type semiconductor substrate, a first N type region extending through the P type semiconductor layer to reach the N type semiconductor substrate, a P type region formed in the first N type region and having a periphery along the outer periphery of the first N type region and a second N type region formed in the P type semiconductor layer. The integrated injection logic semiconductor device is constituted by a PNP lateral transistor utilizing the P type region, the first N type region and the P type semiconductor layer as the emitter, base and collector electrodes respectively, and a NPN vertical transistor utilizing the N type semiconductor substrate, P type semiconductor layer and the second N type region as the emitter, base and collector electrodes, respectively.
