| 摘要 |
A bidirectional thyristor structure with a single MOS gate controlled turn-on and turn-off capability. In a vertical conduction embodiment, the device has a six layer structure including a backside diffusion. One vertical conduction structure includes a single body region at the first surface of the device for conduction in both the forward and reverse directions. Another vertical conduction structure includes a two body regions at the first surface, one for controlling forward conduction and the other for controlling reverse conduction. The vertical conduction embodiments are preferably implemented in a cellular geometry, with a large number of symmetrical cells connected in parallel.
