[0018] Figure 1A and Figure 1B is a diagram showing a semiconductor device according to a first embodiment of the present invention, in which, Figure 1A is the perspective view, and Figure 1B is parallel to Figure 1A A cross-sectional view taken in the YZ plane of , and through the plane of the male terminal 16 (described below). like Figure 1A and Figure 1B As shown, the semiconductor device 1 includes a semiconductor module 10 , a substrate 20 and a connector 30 . In this semiconductor device 1 , the male terminals 16 , 17 which are external connection terminals of the semiconductor module 10 are fitted to the female terminals 31 provided in the connector 30 through the substrate 20 .
[0019] Hereinafter, the semiconductor device 1 will be described. First, the semiconductor module 10, the substrate 20, and the connector 30 will be briefly described, and then, the structure of the portion where the male terminals 16, 17 of the semiconductor module 10 are fitted to...

[0073] In the second embodiment, the hardness (Vickers hardness) of the metal film 163 as the surface treatment material of the male terminal 16 and the hardness of the metal film 312 as the surface treatment material of the female terminal 31 are made different from each other. Specifically, the hardness of the metal film 312 of the female terminal 31 is made higher than the hardness of the metal film 163 of the male terminal 16 . That is, the metal film 312 of the female terminal 31 is made harder than the metal film 163 of the male terminal 16 .
[0074] Image 6 It is a graph showing the relationship between the Vickers hardness and the amount of deformation of the metal film 312 of the female terminal 31 . In this case, the Vickers hardness of the metal film 163 of the male terminal 16 is fixed at 100 Hv. exist Image 6 In , gold films having the same thickness are used as the metal film 163 and the metal film 312. exist Image 6 , the contact pressure P is set to 4N...
