<P>PROBLEM TO BE SOLVED: To provide a device for manufacturing a radiator that can manufacture a radiator while bringing a press blade into even contact with a widening groove, thereby increasing fitting property between fins and a metallic base and reducing thermal contact resistance between the metallic base and fins in the radiator, and to provide a method for manufacturing a semiconductor device. <P>SOLUTION: The device for manufacturing a radiator manufactures the radiator which includes the metallic base 4 and radiator fins 5, and in which the radiator fins are fixed to the metallic base by pushing one end of the radiator fin into an upper groove 4g of a protrusion 4a formed in the metallic base while expanding the upper groove. The device for manufacturing a radiator includes the pressing blade that is moved along the lateral surface of the radiator fin to push and expand the groove and provided therein so as to be movable in a direction perpendicular to the lateral surface of the radiator fin. <P>COPYRIGHT: (C)2013,JPO&INPIT |
