- the heat of the gate electrode 32a can be efficiently cooled by the heat radiation mechanism 62 through the ring gate electrode 37 and the external gate terminal 38, Therefore, it is possible to suppress the in-plane temperature distribution of the semiconductor substrate 32 of the GCT 31 from becoming non-uniform.
- FIG. 5A, 5B, 5C, and 5D will be described below as modified examples of the heat radiation mechanism 62.
- FIG. In Fig. 5A, 62a is a heat radiating mechanism, where the inlet and outlet of the cooling water 66 are both located at one point, and the water flow of the cooling water 66 is divided into two parts at the inlet. It is configured to flow in the water channel 65a provided in a and to join again at the outlet.
- Fig. 5 Smell And 62 b is a heat radiation mechanism, where the inlet and outlet of the cooling water 66 are both located at one place, and the flow of the cooling water 66 goes around the water passage 65 b provided on the gate terminal holding plate 63 b. It is configured as follows. In FIG.
- reference numeral 62c denotes a heat radiation mechanism, which has two inlets and two outlets for the cooling water 66, and the water flow of the cooling water 66 is substantially half the circumference provided on the gate terminal holding plate 63c.
- the water passage 65c is configured so as to make a half circumference in the same direction.
- 62d is a heat dissipating mechanism, which has two inlets and two outlets for cooling water 66, and the flow of cooling water 66 flows almost half way around the gate terminal holding plate 63d. It is configured to make a half circle around 65 d in the same direction in the opposite direction.
- FIGS. 5A, 5B, 5C, and 5D the same operation and effect as in the second embodiment can be obtained.
- the press-contact type semiconductor device is suitable for turning on and off a large current of a main circuit at high speed by gate control. ⁇ SVG (reactive power generation device), etc.
