发明名称 METHOD FOR MANUFACTURING SEMICONDUCTOR CHIP, ADHESIVE FILM FOR SEMICONDUCTOR, AND COMPOSITE SHEET USING THE FILM
摘要 There is provided a method that allows semiconductor chips to be obtained from a semiconductor wafer at high yield, while sufficiently inhibiting generation of chip cracks and burrs. The method for manufacturing a semiconductor chip comprises a step of preparing a laminated body having a semiconductor wafer, an adhesive film for a semiconductor and dicing tape laminated in that order, the semiconductor wafer being partitioned into multiple semiconductor chips and notches being formed from the semiconductor wafer side so that at least a portion of the adhesive film for a semiconductor remains uncut in its thickness direction, and a step of stretching out the dicing tape in a direction so that the multiple semiconductor chips are separated apart, to separate the adhesive film for a semiconductor along the notches. The adhesive film for a semiconductor has a tensile breaking elongation of less than 5% and the tensile breaking elongation of less than 110% of the elongation at maximum load.
