Patent ID: 7098127

Claim:
A method for manufacturing a semiconductor comprising: forming a plurality of electrodes on portions of a semiconductor element forming a first conductive layer by electroless nickel plating on the plurality of the electrodes before applying a layer of a resin in a subsequent step; applying the layer of the resin to the semiconductor element in a region of the semiconductor element that does not include the electrodes, the layer of the resin being applied such that a height of the layer of the resin is greater than a height of the electrodes; forming a second conductive layer over the plurality of the electrodes and the layer of the resin, the second conductive layer being connected to the first conductive layer and covering a top surface of the layer of the resin; patterning the second conductive layer on the electrodes and the layer of the resin in a predetermined pattern; and removing portions of the layer of the resin using the patterned second conductive layer as a mask so that remaining portions of the layer of the resin form a plurality of protrusions.
