Patent ID: 8785256

Claim:
A method of manufacturing a semiconductor package, the method comprising: (a) providing a semiconductor chip having a first surface and a second surface opposite to the first surface, wherein a pad is formed on the first surface; (b) disposing the semiconductor chip on the supporting substrate through a fixing material such that the first surface is directed upward; (c) forming an encapsulation resin layer on the supporting substrate so as to cover the semiconductor chip; (d) polishing the encapsulation resin layer to expose a top surface of the pad; (e) forming an insulating layer on the encapsulation resin layer; (f) forming a wiring layer on the insulating layer, wherein the wiring layer includes a via connected to the pad and a wiring pattern, wherein step (e) and step (f) are alternately repeated; and (g) removing the supporting substrate and the fixing material, wherein the fixing material is a thermally removable adhesive agent, and step (g) includes heating the fixing material after step (f) until the supporting substrate and the fixing material separate from the semiconductor package.
