Abstract:
A sector-shaped wafer piece is processed according to the shape of the piece obtained by dividing a wafer into quarters. Information is collected on the shapes of four patterns of the quarter wafer pieces different in the position of a circular arc of an outer periphery and on processing feed quantities corresponding to the shapes of the four patterns. A pattern is selected by calculating a region of a square having vertical and horizontal sides equal to the two sides of the quarter wafer piece, imaging each of the sides to search for the presence/absence of a target pattern, and selecting that one of the four patterns to which the held quarter wafer piece corresponds. The held quarter wafer piece is processed along division lines with a processing feed quantity corresponding to the selected pattern.

Claim (Index 4):
The processing method for a sector-shaped wafer piece according to  claim 1 , wherein in the processing step, processing is conducted by applying a laser beam along the division lines.
