  • Patent number: 11587831
    Abstract: Provided is a method for machining a workpiece including a substrate that has front and back surfaces and a ductile material layer that contains a ductile material and is disposed on the front or back surface. The method includes a tape bonding step of bonding a tape on a side of the substrate of the workpiece, a holding step of holding the workpiece by a holding table via the tape, and a cutting step of relatively moving the holding table and a cutting blade to cause the cutting blade to cut into the ductile material layer and the substrate. In the cutting step, the cutting blade is rotated such that a portion of the cutting blade, the portion being located on a forward side in a moving direction of the cutting blade relative to the holding table, cuts into the workpiece from the ductile material layer toward the substrate.

  • Patent number: 11569148
    Abstract: In this semiconductor device, a positioning protrusion is formed at a side surface of a sealing resin from which one end of a main electrode wire protrudes. Thus, the outer size of the sealing resin can be reduced as compared to a case where a positioning protrusion is formed at the bottom of the sealing resin. In addition, a thickness regulating protrusion is provided with a space from solder. Thus, it is possible to prevent interface separation or crack that would occur starting from a contact part between the thickness regulating protrusion and the solder, whereby the life of a joining part between a semiconductor module and a cooler can be ensured. Accordingly, a semiconductor device having enhanced heat dissipation property and reliability is obtained without increase in the outer size of the semiconductor module.
