Patent ID: 8404564

Claim:
A method for producing a semiconductor chip comprising the steps 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 in the adhesive film for a semiconductor 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 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, wherein the adhesive film for a semiconductor comprises a polyimide resin that can be obtained by reaction between a tetracarboxylic dianhydride containing 4,4′-oxydiphthalic dianhydride represented by chemical formula (I) below at 50% by mass or greater of the whole, and a diamine containing a siloxanediamine represented by the following general formula (II) below at 30% by mass or greater of the whole, and which can be attached to a semiconductor wafer at 100° C. or below: [In formula (II), R represents a C1-5 alkyl, C1-5 alkoxy, phenyl or phenoxy group, and multiple R groups in the same molecule may be the same or different, while n and m each independently represent an integer of 1-3].
