CMOS-compatible Ti/TiN/Al refractory ohmic contact for GaAs heterojunction bipolar transistors grown on Ge/Si substrate

CMOS-compatible Ti/TiN/Al refractory ohmic contact for GaAs heterojunction bipolar transistors grown on Ge/Si substrate

In this article, we demonstrate the Ti/TiN/Al (15/50/50 nm) ohmic contact on InGaP/GaAs heterojunction bipolar transistors (HBTs) epitaxially grown on 200-mm Si substrate. We study the rapid thermal annealing (RTA) effect of the metal stack on both n-type InGaAs and p-type GaAs. The dc characteristi...
