Abstract:
A plate-shaped workpiece includes a layered body containing metal which is formed in superposed relation to projected dicing lines. The workpiece is processed by holding a layered body side of the workpiece on a first holding table, thereafter, dry etching the workpiece through a mask disposed in areas that are exclusive of the projected dicing lines to form etched grooves along the projected dicing lines in a manner to leave the layered body unremoved, thereafter, holding the layered body side or an opposite side on a second holding table, and thereafter, cutting bottoms of the etched grooves with a cutting blade to sever the workpiece and the layered body along the projected dicing lines. The bottoms of the etched grooves are cut while supplying a cutting fluid containing an organic acid and an oxidizing agent to the workpiece.

Claim (Index 2):
The method according to  claim 1 , wherein said cutting blade has a thickness smaller than the width of said etched grooves.
