Embodiment Construction
[0078] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0079] Such as image 3 , Figure 4 , Figure 5 , Image 6 , Figure 7 with Figure 18 Shown: the present invention takes N-type IGBT as an example to illustrate the structure and corresponding working principle of the present invention.
[0080] Such as Figure 5 As shown, in the top view of the IGBT device, the device includes an active region 15 and a terminal protection region 16 surrounding the active region 15; the active region 15 includes conductive polysilicon 9 arranged in parallel strips, so The conductive polysilicon 9 separates the P well layer 2 in the active region 15 into a P well layer first region 11 and a P well layer second region 12, and the P well layer first region 11 and the P well layer second region 12 alternately and regularly arranged, the first region 11 of the P well layer is provided with an N+ implantation region 10, and a...
