A semiconductor storage deviceincludes a controller packagehaving a BGA terminal on a bottom surface thereof; and one or a plurality of memory packageseach including a plurality of semiconductor storage elements and mounted on the controller package. The controller package includes a bottom substrate having the BGA terminal on a bottom surface thereof; a power supply IC, mounted on the bottom substrate, for supplying a plurality of power supplies; and a controller mounted on the bottom substrate and operable by the plurality of power supplies supplied from the power supply IC. The controller provides an interface with an external system via the BGA terminal and controls a read operation from the semiconductor storage elements and a write operation to the semiconductor storage elements.

Semiconductor storage device and method for producing the same

A semiconductor device containing: a semiconductor element; a support substrate; an insulating material layer for sealing the semiconductor element and a periphery thereof; a metal thin film wiring layer provided in the insulating material layer, with a part thereof being exposed on an external surface; and metal vias provided in the insulating material layer and electrically connected to the metal thin film wiring layer. The semiconductor element is provided in a plurality of units and the respective semiconductor elements are stacked via an insulating material such that a circuit surface of each semiconductor element faces the metal thin film wiring layer, and electrode pads of each semiconductor element are exposed without being hidden by the semiconductor element stacked thereabove.
