Abstract :
An n-channel BICFET in the InGaAs/InAlGaAs/InAlAs material system with a current gain in a large-area device of greater than 900 is discussed. The device structure utilizes a self-aligned refractory emitter contact and high-temperature processing and still obtains an ideality factor of 1.2 for the source input diode.<>
