Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device comprising:
a semiconductor chip having a first face and a second face on an opposite side to the first face, and including semiconductor elements on the first face;
columnar electrodes provided above the first face, and electrically connected to any of the semiconductor elements;
a first member located. around the columnar electrodes above the first face;
a first resin layer provided between the first member and the first face and directly connected with a face of the first member which is opposite to the first face; and
a second resin layer covering the columnar electrodes and the first member, wherein
the first member is harder than the columnar electrodes and the second resin layer, and
the first member and the columnar electrodes are exposed from a surface of the second resin layer,
a height of a lower end of the first member is higher than a height of lower ends of the columnar electrodes,
a thickness of the first member is thinner than a thickness of the second resin layer,
the first resin layer and the second resin layer contact directly,
surfaces of the first member, the columnar electrodes and the second resin layer are substantially flush with each other, and
a height of the lower end of the first resin layer is higher than a height of the lower ends of the columnar electrodes.
