Abstract:
Provided is a technique for improving product attachment. In a semiconductor device, the following expression is satisfied by an angle A formed by an imaginary line connecting two attachment holes together and an imaginary line connecting together a lowest point of one of two projections positioned in a surrounding portion of one of the two attachment holes and a contact point between a bulge and a heat sink, with a screw fastened to the heat sink through the one attachment hole, where M represents a vertical direction between the lower end of a body and the lower end of a case, where W represents a bulge amount of the bulge, where T represents a height of the projection, where L represents a horizontal distance from the outer peripheral end of the case to the outer peripheral end of the heat dissipation plate: 0<A<arctan ((M+W−T)/L).

Claim (Index 1):
A semiconductor device comprising:\n a heat sink; a heat dissipation plate disposed above the heat sink; a semiconductor element disposed above the heat dissipation plate; and a case enclosing the semiconductor element and attached to the heat sink, wherein the heat dissipation plate has\n a body being flat shaped, and \n a bulge bulging out from a lower end of the body in a form of an arc in cross-sectional view, \n wherein the case has\n an attachment portion extending outward from an outer periphery portion at a lower end portion of the case, \n two attachment holes disposed in positions opposite to each other in the attachment portion, and provided for attachment to the heat sink, and \n two projections individually projecting downward from a lower surface of the attachment portion in positions more adjacent to an outer periphery side of the attachment portion than the two attachment holes, and \n wherein the following expression is satisfied by an angle A formed by an imaginary line connecting the two attachment holes together and an imaginary line connecting together a lowest point of one of the two projections positioned in a surrounding portion of one of the two attachment holes and a contact point between the bulge and the heat sink, with a screw fastened to the heat sink through the one attachment hole, where M represents a vertical distance between the lower end of the body and the lower end of the case, where W represents a bulge amount of the bulge, where T represents a height of the projection, where L represents a horizontal distance from an outer peripheral end of the case to an outer peripheral end of the heat dissipation plate:\n 0< A <arctan(( M+W\u2212T )/ L ).
