<p>PURPOSE:To prevent the displacement of the positions between a semiconductor element and a contacting electrode plate by holding by a U-shaped clip a supporting plate of a semiconductor substrate, on which both gate and cathode electrodes are disposed without providing an irregular surface on a main surface, and a contacting electrode plate formed with an escape such as a through hole or a groove. CONSTITUTION:A stationary groove 22 for mounting a clamp to prevent the rotation is provided in the vicinity of the outer periphery of the surface of a contacting electrode plate. The contacting plate 6 and a semiconductor element formed of a silicon substrate 1 and a supporting plate 5 are secured with a U- shaped clamp 23 having a hook at the end formed of an insulating member such as rubber or Teflon. In this case, a groove 24 is formed similarly to the groove 22 of the plate 6 in the vicinity of the outer periphery of the surface of the plate 5. Thus, the clamp 23 is engaged with the stationary grooves 22, 24, thereby matching the plate 6 and the element at the relative positions to thereafter inhibit them to solely move.</p> |
