Abstract :
In the present work the reliability of Carbon-doped GaInP/GaAs HBTs is evaluated by means of a current stress performed at room temperature. The impact of the stress on DC and RF characteristics and low frequency noise is reported, and a correlation between DC, RF, and noise variations is demonstrated. The effects observed are explained in terms of Carbon passivation by Hydrogen atoms released from passivation/semiconductor interface during the stress
