【Abstract】 Through numeral simulation, the inner electric field, carrier distribution and output property of a new type PNP transistor are obtained. The width of effective base region of the transistor is about 50 nm. It is proved that the electric field in the effective base region is the main cause for the minority carrier to move. The output property of the transistor is almost the same as that of MOS field effect transistor. This transistor is expected to be a high speed device in digital circuits.更多还原
