An assembled semiconductor device comprising a base constituting one electrode, a semiconductor pellet mounted on the base, an insulation ring located to surround the semiconductor pellet and having a height larger than the thickness of the semiconductor pellet, an electrode member mounted on the insulation ring and in electrical contact with the upper surface of the semiconductor pellet, a lead electrode disposed on the electrode member, a pressure plate mounted on the lead electrode through an insulation member or being formed of an insulation material and disposed on the lead electrode, a bolt screwed into the base, and a pressing device which presses the semiconductor pellet through the pressure plate. The inventive device simplifies the assembling process, makes the maintenance easy, and improves the air-tightness for the semiconductor pellet.
