摘要:
The minimum emitter-base contact spacing necessary to prevent current gain degradation is discussed for Npn heterojunction bipolar transistors designed for high-speed applications. Theoretical calculations are performed for various base doping levels, base thicknesses, and emitter widths. These results indicate that the minimum spacing for different design parameters varies between 400 angstrom and 1300 angstrom.
