Embodiment Construction
[0027] As mentioned in the background section, semiconductor devices in the prior art are prone to failure and have poor performance.
[0028] The inventors found that there are two main reasons why existing semiconductor devices are prone to failure: on the one hand, during the turn-on and turn-off processes of the semiconductor device, the base region close to the main junction in the active region of the semiconductor device is prone to latch-up Lock-in effect, causing semiconductor devices to fail. On the other hand, when the semiconductor device is subjected to a reverse voltage, the main junction of the semiconductor device is prone to premature breakdown, resulting in failure of the semiconductor device.
[0029] The inventors have found that the main reason for the latch-up effect to occur easily in the base region close to the main junction in the active region of the semiconductor device is that there will be a large dynamic avalanche current during the turn-on and t...
