Abstract :
A high-gain gate-assisted lateral bipolar n-p-n transistor with current gain of over 3000 was fabricated in a compatible p-well CMOS process. The device was fabricated using the same mask sequences as that of an n-channel MOSFET with its gate connected to the p-well. With the assistance of the PISCES device simulator, total collector current was found to have two main components, the gale-assisted component and the bulk bipolar component. A circuit model with parallel MOSFET and bipolar transistors was used to verify DC measurement results
