Patent ID: 8378473

Claim:
A semiconductor device comprising: a first layer; a second layer over the first layer, the second layer having a hole; a connection electrode over the first layer; a semiconductor chip fixed to a surface of the first layer and electrically connected to the connection electrode; a penetration electrode which penetrates the second layer and is electrically connected to the connection electrode; a base material over the second layer; and an antenna over the base material, the antenna electrically connected to the penetration electrode, wherein the semiconductor chip is provided between the first layer and the base material, wherein a first gap between a first inner side surface of the second layer and a first side surface of the semiconductor chip is smaller than a width of the semiconductor chip, wherein a second gap between a second inner side surface of the second layer and a second side surface of the semiconductor chip is smaller than a width of the semiconductor chip, and wherein the first inner side surface faces to the second inner side surface.
