Semiconductor device manufacturing method and manufacturing apparatus

An apparatus for manufacturing a semiconductor device including a wiring substrate having a first region where a semiconductor chip is mounted and a second region around the first region, and terminals extending from the first region to the second region formed on one surface thereof, comprising:

• a cutting section that cuts the wiring substrate;
• wherein a reinforcing member is provided on another surface of the wiring substrate, the reinforcing member overlapping the terminals and a part of the reinforcing member protrudes from the first region to the second region;
• and
• wherein the cutting section includes:
• a first cutting section cutting the terminals along a boundary between the first region and the second region by punching through from a surface side having the terminals in the wiring substrate;
• and
• a second cutting section continuously cutting the reinforcing member from an inboard side to an outboard side along the boundary between the first region and the second region by punching through from a surface side having the reinforcing member in the wiring substrate.
