Patent ID: 7132749

Claim:
A semiconductor device comprising: a circuit substrate; a plurality of electrodes provided directly on the circuit substrate; a passivation film; a plurality of protrusions which protrude higher than the electrodes, said protrusions being made of a resin and being spaced in a predetermined pattern away from the electrodes; and a conductive layer comprising a plurality of portions, each of the portions being electrically connected to one of the electrodes and covering a top surface of one of the protrusions, said conductive layer having sufficient characteristics and being configured to serve as a mask for removing excess resin between the portions of the conductive layer from a surface of the semiconductor device, wherein: the electrodes are aligned with a predetermined pitch and the passivation film has openings for the electrodes; the protrusions are disposed in regions except immediately above the openings with the same pitch as that of the electrodes; and the portions of the conductive layer electrically connect the electrodes through the openings and cover the top surfaces of the protrusions.
