Definitions
- This disclosure relates to a semiconductor device, and in particular to a semiconductor device having a package structure with a metal base plate and a resin case.
- Patent Document 1 discloses a semiconductor device having a package structure with a metal base plate for heat dissipation and a resin case.
- the metal base plate and the resin case are joined by pressing the resin case against the metal base plate to which an adhesive has been applied, and then heating the metal base plate to harden the adhesive.
- one method of pressing the resin case against the metal base plate is to fasten the metal base plate and the resin case together with a jig on which the resin case is placed using screws.
- the metal base plate and the resin case are heated while they are screwed together to harden the adhesive, and then the screws fastening the metal base plate and the resin case together are removed.
- the torque used to tighten the first screw can cause the resin case to shift relative to the metal base plate, centered around the tightening position of the first screw. If the adhesive hardens while the resin case and metal base plate are misaligned, the fastening holes in the resin case and the metal base plate will be misaligned in the finished semiconductor device. If there is such misalignment of the fastening holes, the screw will interfere with the inner wall of the fastening hole in the metal base plate when fixing the semiconductor device to the cooling fin, causing problems with attaching the cooling fin.
- This disclosure has been made to solve the above problems, and aims to provide a semiconductor device that can prevent misalignment between the fastening holes in the resin case and the fastening holes in the metal base plate.
- the semiconductor device comprises a semiconductor element, an insulating substrate on which the semiconductor element is mounted, a metal base plate on which the insulating substrate is mounted, a resin case provided on the metal base plate so as to surround the insulating substrate, a plurality of first fastening holes formed in the metal base plate, a plurality of second fastening holes formed in the resin case and arranged so as to overlap the first fastening holes, and a protrusion provided in an area between adjacent first fastening holes of the metal base plate for limiting rotation of the resin case.
- the metal base plate is provided with a protrusion that limits the rotation of the resin case, thereby preventing misalignment between the first fastening hole in the resin case and the second fastening hole in the metal base plate.
