LONG life is a design goal for many semiconductor processes. But it is a go
al that is apparently well met by a line of gallium-arsenide (GaAs) heteroj
unction bipolar transistors (HBTs) from EiC Corp. (Fremont, CA). Fabricated
with indium-gallium-phosphide (InGaP) emitters, these GaAs integrated circ
uits (ICs) meet the needs of modern, communications systems for smaller die
sizes, better reliability, and better device-to-device repeatability.
