Abstract

A semiconductor package includes: a build-up wiring layer including a metal wiring layer and an insulation resin layer; and a low thermal expansion material layer having a coefficient of thermal expansion closer to that of a semiconductor chip mounted on the build-up wiring layer as compared with the insulation resin layer of the build-up wiring layer, the low thermal expansion material layer being bonded to an entire region of a rear surface of the build-up wiring layer corresponding to a region of a front surface of the build-up wiring layer on which the semiconductor chip is mounted.
