Effects of the doping profile on current characteristics in BSITs

Proposed are two doping profiles of the conducting channel in bipolar-mode static induction transistors (BSITs) that improve the current handling capability. By using the results obtained from two-dimensional device simulations, it is shown that BSITs with the proposed profiles exhibit higher drain current density and DC current gain than conventional BSITs. Also discussed is the tradeoff between the current and voltage capabilities.<
