ABSTRACT:
A method for manufacturing a semiconductor device is provided including: providing a reinforcing member on one surface of a wiring substrate that has a first region where a semiconductor chip is mounted and a second region around the first region, and has terminals extending from the first region to the second region formed on another surface thereof, in a manner that the reinforcing member overlaps the terminals and a part thereof protrudes from the first region to the second region; punching through from a surface side having the reinforcing member in the wiring substrate, thereby continuously cutting the reinforcing member from an inboard side thereof to an outboard side along a boundary between the first region and the second region; and punching through from the surface side having the reinforcing member in the wiring substrate, thereby cutting the terminals along the boundary between the first region and the second region.
