Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To secure sufficient transverse rupture strength by chamfering at least one portion of a chip edge part for composing the reverse side of a circuit forming surface. SOLUTION: Polishing machining, using an elastic pad 7 and slurry 8, is made. Elastic polyurethane is applied to the elastic pad 7, and a material that is made of a silica fine particles, amine additives, dispersants, and pure water is applied to the slurry 8. By using the elastic pad 7 and the slurry 8 and polishing semiconductor chips 3a, 3b, 3c,..., 3n that have been formed into individual pieces in advance, load concentration caused by the elastic operation of the elastic pad 7 occurs at a chip edge part, thus increasing removing rate at the chip edge part and performing chamfering for rounding the chip edge part. Amine additives have the action of chemically etching the semiconductor chips 3a, 3b, 3c,..., 3n, so that the action of chemical etching is also taken into consideration.
