Congratulations to Dr. Donald Cheng for winning Best Student Paper at CSMANTECH 2011 for his paper titled, “Type-II DHBTs Microwave Characterization and Metallization Issues”. This paper described the problem of emitter-to-base shorts during the fabrication of Type-II submicron DHBTs. He presented designs of experiment to identify the problem, as well as the solution to the problem. Ultimately, the BE shorts were minimized, and devices were fabricated with room temperature current gain cutoff frequency (fT) up to 680 GHz.
