Abstract
Official abstract text for this publication.
A design method includes a process of preparing plural cutting members having different degrees of taper in a tip portion thereof, a process of preparing plural grooves on a front surface side having the same shape, a process of confirming a breakage status when a groove on a rear surface side is formed by the plural cutting members, and a process of selecting, when it is confirmed that both of a cutting member that causes breakage and a cutting member that does not cause the breakage are included, the degree of taper of the cutting member that does not cause the breakage as a tip shape of a cutting member to be used in a mass production process.
First claim
Opening claim text (preview).
What is claimed is: 1. A design method of a tip shape of a cutting member used in a semiconductor piece manufacturing method including forming a groove on a front surface side on a front surface of a substrate, and forming a groove on a rear surface side that communicates with the groove on the front surface side by a rotating cutting member that has a thickness larger than the width of the groove on the front surface side from a rear surface of the substrate and individualizing…
