Patent ID: 7427812

Claim:
A semiconductor device comprising: a semiconductor substrate having a top surface which has a quadrangular shape; a plurality of connection pads formed on the top surface of the semiconductor substrate; an insulation film formed on the top surface of the semiconductor substrate except the connection pads; a plurality of external connection electrodes formed on the insulation film so as to be connected to the connection pads; and a sealing film provided in between the external connection electrodes; wherein the plurality of external connection electrodes comprise a first group of external connection electrodes which are arranged in first lines running along two diagonal lines of the semiconductor substrate and a second group of external connection electrodes which are arranged in second lines running along the first lines outside of the first lines with respect to the diagonal lines; and wherein an upper insulation film having openings corresponding to the external connection electrodes is formed on the sealing film and the external connection electrodes, and upper wires which are connected to the external connection electrodes are formed on the upper insulation film.
