Abstract :
We demonstrate molecular-beam epitaxy (MBE)-grown heterojunction bipolar transistors (HBTs) on InP substrates with a patterned implant n+ subcollector below the epitaxial layers. Device layers grown on implanted/annealed substrates were of similar quality to those on virgin InP. Maximum ft and fmax of 240 and 310 GHz were obtained. We present the process flow, details of the ion implantation, layer characterization, and device results.
