  • Abstract
    Improved high-frequency performance in vertical bipolar transistors in which the active base region is fabricated with focused ion beam (FIB) lateral doping profiles is demonstrated. Profiles which reduce base resistance, current crowding, and high-level injection effects have the most significant effect on high-frequency characteristics.
