Abstract
Bump electrodes (conductive members) bonded onto lands disposed at a peripheral portion side than terminals (bonding leads) electrically coupled to pads (electrode pads) of a microcomputer chip (semiconductor chip) are sealed with sealing resin (a sealing body). Thereafter, the sealing resin is ground (removed) partially such that a part of each of the bump electrodes is exposed. The step of protruding the part of each of the bump electrodes from a front surface of the sealing resin is performed, after the grinding step.
