Abstract
A novel approach for realising a double heterojunction bipolar transistor (DHRT) with a low base resistance, which incorporates a thick extrinsic base and a regrown emitter is proposed and demonstrated. A combination of selective MOVPE regrowth and selective wet chemical etching resulted in a new self-aligned DHBT structure. Fabricated microwave transistors exhibited good DC and microwave characteristics
