Abstract
The present invention relates to a technique of semiconductor devices, and provides a semiconductor device, which uses two controllable current sources to control the electron current and the hole current of the voltage-sustaining region of a thyristor under conduction state, making the sum of the two currents from anode to cathode close to a saturated value under high voltage, thus avoiding the current crowding effect in local region and increasing the reliability of the device. Besides, it further provides a method of implementing the two current sources in the device and a method to improve the switching speed.
