12. A method for manufacturing a semiconductor device in which a plurality of semiconductor modules, each of the plurality of semiconductor modules comprising a circuit board having at least one or more semiconductor chips mounted thereon and an attachment hole, are arranged and held in a module storage case, the method comprising:
-
inserting a main connection terminal protruding from each of the plurality of semiconductor modules into an insertion hole of a connection terminal holding portion formed in a main terminal plate traversing the plurality of semiconductor modules, with the plurality of semiconductor modules arranged in parallel, and fixing the main connection terminal and the connection terminal holding portion to form a module aggregate; accommodating and holding the module aggregate in the module storage case such that a bending plate portion of the main terminal plate protrudes toward the outside through an attachment insertion hole of the module storage case, the position of the semiconductor modules being adjustable during attachment, thereby forming a semiconductor device; and mounting the module storage case on a cooler and inserting fixing tools into the attachment holes of the plurality of semiconductor modules through insertion holes disposed in the module storage case, thereby fixing each of the accommodated plurality of semiconductor modules to the cooler. - View Dependent Claims (13)
