Patent ID: 8017503

Claim:
A manufacturing method of a semiconductor package, comprising: forming a semi-cured insulation layer made of a photosensitive material on a supporting body; forming an opening part in the insulation layer by a photolithography method, the opening part being configured to expose the supporting body; arranging a semiconductor chip on the insulation layer so that a position of an electrode of the semiconductor chip is consistent with a position of the opening part, and curing the insulation layer; forming sealing resin on a surface of the insulation layer at a side of the insulation layer with the semiconductor chip, the sealing resin being configured to seal the semiconductor chip; removing the supporting body; and subsequent to the steps of forming a semi-cured insulation layer and removing the supporting body, providing a wiring layer on a surface of the insulation layer opposite to the side of the insulation layer with the semiconductor chip; and electrically connecting the wiring layer to the electrode exposed in the opening part, thereby forming a wiring structural body including the insulation layer and the wiring layer.
