INTEGRATED CIRCUIT SEMICONDUCTOR DEVICE

摘要

The device structure is a bi-polar transistor having a region of inert atoms located in the collector adjacent to the base-collector junction. Another embodiment of the invention is a complementary insulated gate field effect transistor (IGFET) structure having N and P channel IGFETs with regions of implanted ions beneath the source and drain of one or both transistors, and/or annular regions projecting inwardly from the surface that surround or separate the different types of IGFETs.
