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. |
