  • Abstract
    A new structure for AlGaAs/GaAs heterojunction bipolar transistors (HBTs) that employs a buried proton-implanted external collector layer is proposed. This structure has been successfully used to achieve high-performance HBTs with maximum oscillation frequencies fmax up to 51 GHz for a device with 2 ¿×5 ¿m emitter and 4 ¿m×7 ¿m collector dimensions.
