Abstract:
1. A method for manufacturing a semiconductor device, comprising the steps of: (a) 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, the reinforcing member overlapping the terminals and a part of the reinforcing member protrudes from the first region to the second region; (b) punching through from a surface side having the terminals in the wiring substrate to cut the terminals along a boundary between the first region and the second region; and (c) punching through from a surface side having the reinforcing member in the wiring substrate to continuously cut the reinforcing member from an inboard side to an outboard side along the boundary between the first region and the second region.
