摘要

A power semiconductor package is provided. The power semiconductor package includes a chip, leads, conductive media, and a molding material. The leads have a groove in the shape of a hemisphere or a down-set. The package further includes an adhesive. The package can increase solder joint reliability and thermal performance. Also, the size of the package can be reduced, and sawing can be performed so that a burr does not occur.
