Embodiment 1
[0034] see figure 1 (a) and figure 1 (b) and image 3 (a), the first emitter E1 is electrically connected to the first active region 110; the first gate region 130 is disposed on the first active region 110; the first gate G1 is connected to the first active region 110; A gate region 130 is electrically connected. In this embodiment, the device body Q1 and the detection device T1 have a common gate, that is, the first gate G1; the second active region 120 is disposed on the periphery of the first active region 110 , constituting a detection device T1 for performing a temperature detection function; the second emitter E2 is electrically connected to the second active region 120; the collector region 160 is connected to the first active region 110 and the second active region 120 electrical contacts (see Figure 5 ), and located on the back of the device body Q1 of the power device; the collector C is electrically connected to the collector region 160, and in this embodiment,...
Embodiment 2
[0039] refer to figure 2 (a) and figure 2 (b) and image 3 (b), on the basis of the first embodiment, the power device 10 is further provided with a second gate region 150 and a second gate G2, and the second gate region 150 is arranged in the second active region 120 above; the second gate G2 is electrically connected to the second gate region 150 . At this time, the device body Q1 and the detection device T1 of the power device 10 have different gate regions, and their on-off is also controlled by different gates. The gate region of the device body Q1 is the first gate region 130 . The control electrode is the first gate G1; the gate region of the detection device T1 is the second gate region 150, and the control electrode is the second gate G2.
[0040] In this embodiment, when the control electrodes (gates) of the device body Q1 and the detection device T1 are different, they are the first gate G1 and the second gate G2 respectively. When the system is in the tempera...
