  • Method of manufacturing a semiconductor device
    Patent number: 10998246
    Abstract: Reliability of a semiconductor device is improved. A method of manufacturing a semiconductor device includes a step of preparing a lead frame in which a plurality of device forming regions are arranged in a matrix, a die bonding step of mounting a semiconductor chip on each device region, a resin sealing step of individually covering each semiconductor chip with a sealing body, and a lead plating step of plating an outer portion of a lead exposed from the sealing body. Between the resin sealing step and the lead plating step, an inspection step for detecting defective products in the resin sealing step and a defective product removal step for removing a device region of defective products are provided.
    Type: Grant
