Abstract

It is known that the performance, that is device speed, of the bipolar transistor can be improved by reducing the emitter thickness. However, it is also known that a reduction in emitter thickness causes a degradation in the current gain. The process described herein and the resulting structure decrease the emitter thickness without unduly reducing the current gain of an NPN transistor. ***** THIS IS AN ABSTRACT - (Image Omitted)
