Abstract: | A Novel MOS|gated thyristor, depletion|mode MOS gated emitter shorted thyristor (DMST),and its two structures are proposed.In DMST,the channel of depletion|mode MOS makes the thyristor emitter|based junction inherently short.The operation of the device is controlled by the interruption and recovery of the depletion|mode MOS P channel.The perfect properties have been demonstrated by 2|D numerical simulations and the tests on the fabricated chips. |
