Abstract
A semiconductor device which stores a plurality of semiconductor chips, having planar sizes which differ, in the same sealing body in a state in which they are accumulated via an insulating film which has an adhesive property. In the semiconductor device, the thickness of DAF of the back surface of the uppermost semiconductor chip with which the control circuit is formed is thicker than each of DAF of the back surface of the lower layer semiconductor chip with which the memory circuit is formed.
