Claim Text:
1. A semiconductor device comprising: a semiconductor package including a semiconductor integrated circuit, an interlayer film disposed on the semiconductor integrated circuit, a rewiring layer disposed on the interlayer film, post electrodes disposed on the rewiring layer, a protective layer which is disposed on the interlayer film and covers the rewiring layer and the post electrodes, and a plurality of balls which is respectively disposed on the post electrodes and is connected to the rewiring layer; and a printed circuit board substrate including an insulating substrate, a plurality of lands which is arranged on the insulating substrate to face the plurality of balls and is respectively connectable to the plurality of balls, and wirings which are arranged on the insulating substrate and are respectively connected to the plurality of lands, wherein balls existing on a wiring path of internal wirings, which are connected to lands arranged in the inside on the insulating substrate, are removed, wherein the internal wirings are formed between balls adjacent to each other when viewed from top, and wherein between the adjacent balls, a center of the rewiring layer and centers of the internal wirings deviate from each other when viewed from top.
