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 2):
The processing method for a sector-shaped wafer piece according to  claim 1 ,\n wherein the pattern selection step includes:\n a target pattern detection step of calculating a region of a square having vertical and horizontal sides equal to two sides of the quarter wafer piece, searching for the target pattern in the device at a center of each of the four sides of the square by the imaging unit, and detecting the target patterns from the two sides of the quarter wafer piece; and \n a selection step of selecting, based on the positions of the sides where the target pattern has been detected, that one of first quadrant, second quadrant, third quadrant, and fourth quadrant of the wafer in an XY rectangular coordinate system before quadrisection to which the quarter wafer piece corresponds.
