Abstract

There is provided a method of manufacturing a semiconductor package. The method includes: (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 a supporting substrate 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; and (d) polishing the encapsulation resin layer to expose a top surface of the pad.

Claims (21)

1. A semiconductor package comprising:

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;

an encapsulation resin layer covering the semiconductor chip such that a top surface of the pad is exposed from one surface of the encapsulation resin layer;

an insulating layer formed on the encapsulation resin layer; and

a wiring layer formed on the insulating layer to be electrically connected to the pad,

wherein a multilayer structure comprising a plurality of insulating layers and a plurality of wiring layers are formed on the encapsulation resin layer, and

wherein a thickness of the encapsulation resin layer is larger than that of the multilayer structure.

2. The semiconductor package according to claim 1 , wherein the top surface of the pad is substantially flush with the one surface of the encapsulation resin layer.

3. The semiconductor package according to claim 1 , wherein the second surface of the semiconductor chip is exposed from the other surface of the encapsulation resin layer.

4. A semiconductor package comprising:

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;

an encapsulation resin layer covering the semiconductor chip such that a top surface of the pad is exposed from one surface of the encapsulation resin layer;

an insulating layer formed on the encapsulation resin layer; and

a wiring layer formed on the insulating layer to be electrically connected to the pad,

wherein the top surface of the pad is substantially flush with the one surface of the encapsulation resin layer.

5. A semiconductor package comprising:

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;

an encapsulation resin layer covering the semiconductor chip such that a top surface of the pad is exposed from one surface of the encapsulation resin layer;

an insulating layer formed on the encapsulation resin layer; and

a wiring layer formed on the insulating layer to be electrically connected to the pad,

wherein the second surface of the semiconductor chip is exposed from the other surface of the encapsulation resin layer.
