Patent ID: 7759164

Claim:
A method of manufacturing a semiconductor device comprising the steps of: (a) affixing a dicing film to a back surface of a semiconductor wafer; (b) after the step (a), dicing the semiconductor wafer to divide the semiconductor wafer into a plurality of semiconductor chips; and (c) after the step (b), sticking up a back surface of the dicing film by a stick-up means of a pickup means to suck the stuck-up semiconductor chips, thereby separating the semiconductor chips from the dicing film, the stick-up means comprising a pickup element and a pickup unit accommodated in an interior of the pickup element, the pickup unit comprising a plurality of needles having tips for contact with the back surface of the dicing film, a magnet for fixing rear ends of the plural needles, and a needle holder which includes a plurality of through holes each having an inside diameter slightly larger than the diameter of each of the needles and controls the attitude of the needles inserted respectively into the plural through holes, a length of the needle holder being shorter than a length of the needles, the pickup element having an upper surface including a plurality of openings for allowing the tips of the needles to project from the upper surface of the pickup element in the step (c), the back surface of the dicing film being pushed up by the tips of the needles in the step (c).
