ABSTRACT:
A method for fabricating a semiconductor apparatus using a board frame. A wiring board region of the frame includes an island on which a semiconductor device is mounted. A marginal region of the frame surrounds the wiring board region. A frame region is located around the marginal region. A support region extends between the wiring board region and the frame region to connect the wiring board region and frame region together through the support region. The marginal region is removed from the board frame and then put back to its original position, while maintaining the wiring board region connected to the frame region through the support region. Then, the device is mounted onto the island. Next, transfer-molding is performed on the device using a die set that includes a gate through which a thermosetting resin is guided into a cavity. Then, the marginal region is removed completely from the board frame.
