We report a merged n-HJFET/Pnp-HBT technology for high-speed circuits.
This technology is based upon using the p(+) junction gate of the n-H
JFET as the emitter of the Pnp-HBT. The channel of the FET is used as
the base and the p-buffer functions as the collector facilitating the
fabrication of both devices from the same epilayer structure. (C) 1996
