Abstract
GaInP/GaAs Heterojunction Bipolar Transistors (HBT's) have been fabric ated on epitaxial layers grown by Chemical Beam Epitaxy (CBE) using an all metalorganic approach. Reduced toxicity tertiarybutylarsine (TBA) and tertiarybutylphosphine (TBP) were used for group V Sources. DC re sults showed good base and collector current ideality factors of 1.23 and 1.05 respectively. The maximum de current of 50 was obtained. A co mparison of these results with HBT characteristics obtained using AsH3 /PH3 or TBA/PH3 demonstrates the feasibility of replacing the toxic As H3 and PH3 by less toxic TBA and TBP sources in the growth of GaInP/Ga As HBT's.
