ABSTRACT:
A compression type semiconductor device includes a semiconductor element; at least one metal plate having substantially upright edge surfaces, a planar contacting surface engaging a first surface of the semiconductor element and a continuous curved surface interconnecting the edge surfaces and the contacting surface; and a means for pressing the contacting surface of the metal plate against the first surface of the semiconductor element. The continuous curved surface of the metal plate is so formed that at each point on the periphery of the contacting surface at least one plane normal to the contacting surface intersects the curved surface in an arcuate curve which tangentially joins the contacting surface.
