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 1):
A method of processing a plate-shaped workpiece that includes a layered body containing metal which is formed in superposed relation to projected dicing lines, comprising the steps of:\n holding a layered body side of said workpiece on a first holding table; thereafter, performing dry etching on said workpiece through a mask disposed in areas that are exclusive of said projected dicing lines thereby to form etched grooves in said workpiece along said projected dicing lines in a manner to leave said layered body unremoved; thereafter, holding the layered body side of said workpiece or a side of said workpiece which is opposite the layered body side thereof on a second holding table; and thereafter, cutting bottoms of said etched grooves with a cutting blade to sever said workpiece and said layered body along said projected dicing lines; wherein the step of cutting the bottoms of said etched grooves includes the step of cutting the bottoms of said etched grooves while supplying a cutting fluid containing an organic acid and an oxidizing agent to said workpiece.
