Abstract:
A method of securing semiconductor chips, comprising the steps of:providing a transfer tape comprising a base material and an adhesive superimposed upon the base material at spaced-apart intervals, wherein the adhesive is in the form of a pattern of independent constituents whose respective areas are substantially equal to each other, the area per pattern constituent is in the range of 0.01 to 10% of the area of an underside of a semiconductor chip onto which the adhesive is transferred, and an average shortest distance between pattern constituents is in the range of 0.5 to 10% of a maximum length of the semiconductor chip underside; sticking backs of semiconductor chips to the transfer tape; peeling the semiconductor chips from the transfer tape in such a manner that the adhesive is transferred onto the backs of the semiconductor chips; and securing the semiconductor chips through the adhesive onto a substrate.
