Abstract:
A base plate having concave curved portions (rearward-convex parts) curved in a rearward direction to be convex and have a predetermined curvature, is fixed to a surface of a cooling fin while being in contact with the surface of the cooling fin at vertices of the rearward-convex parts. A stacked substrate is bonded on a front surface of the base plate, at an area opposing the rearward-convex part. A spacer is provided on a rear surface of the base plate, at a position closer than an edge of a solder layer to a perimeter of the base plate. The spacer is sandwiched between the base plate and the cooling fin when a screw for fixing the base plate to the cooling fin is tightened and the spacer has a function of suppressing deformation of the base plate.

Claim (Index 18):
A method of manufacturing a semiconductor device, the method comprising:\n preparing a stacked substrate on which a semiconductor chip is mounted, a base plate, and a cooling fin, the base plate having a bonding area of a front surface of the base plate, and a through hole being closer to a perimeter of the base plate than is the bonding area, the cooling fin having a spacer provided closer to a perimeter of the cooling fin than is an area corresponding to the bonding area of the base plate, the spacer protruding by a predetermined height from a front surface of the cooling fin; bonding a rear surface of the stacked substrate to the bonding area of the front surface of the base plate so as to curve the base plate forming a concave curved portion at the bonding area of the front surface of the base plate; inserting a screw in the through hole of the base plate while a vertex of the concave curved portion of a rear surface of the base plate is in contact with the front surface of the cooling fin; and engaging the screw with a screw hole of the cooling fin until the spacer is in contact with the base plate, thereby fixing the base plate to the cooling fin.
