Abstract:
A semiconductor package adapted for connection to an external device, comprising:a package base; package terminals formed in the package base and adapted for connection to the external device; a wiring layer formed on the package base and electrically connected to the package terminals; a semiconductor chip mounted on the package base and electrically connected to the wiring layer; a low-elasticity resin layer formed between a resin mold and the wiring layer and between the package base and the resin mold, and extending from a rim inward to a predetermined extent being back from the outer edge of the semiconductor chip, and an end face of the low-elasticity resin layer being exposed at the outer edge of the semiconductor package; and the resin mold sealing the package base, the wiring layer, the semiconductor chip, and the low-elasticity resin layer; and the low-elasticity resin layer having a lower elasticity modulus than the resin mold.
