Abstract
A semiconductor device which eliminates a thermal stress in the semiconductor device or warp in a package of the semiconductor device to increase reliability. To achieve this, the semiconductor device has a structure in which an insulation flexible film and a semiconductor chip are stuck together. The insulation flexible film has on the obverse side a plurality of electrode pads and, on the reverse side, a plurality of electrodes electrically connected to the plurality of electrode pads. The semiconductor chip is sealed on the chip-mounting side of the insulation flexible film with resin, with a thickness of the resin above the semiconductor chip equal to or less than the thickness of the semiconductor chip.
