Abstract:
A method of processing a plate-shaped workpiece that includes layered bodies containing metal which are formed in superposed relation to projected dicing lines includes the steps of holding the workpiece on a first holding table such that the layered bodies are exposed, thereafter, cutting the workpiece along the projected dicing lines with a cutting blade to form cut grooves that sever the layered bodies, thereafter, holding the workpiece on a second holding table such that a mask disposed in areas that are exclusive of the projected dicing lines is exposed, and thereafter, performing dry etching on the workpiece through the mask to sever the workpiece along the projected dicing lines. The step of cutting the workpiece includes the step of cutting the workpiece 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 layered bodies containing metal which are formed in superposed relation to projected dicing lines, comprising the steps of:\n holding said workpiece on a first holding table such that said layered bodies are exposed; thereafter, cutting said workpiece along said projected dicing lines with a cutting blade to form cut grooves that sever said layered bodies; thereafter, holding said workpiece on a second holding table such that a mask disposed in areas that are exclusive of said projected dicing lines is exposed; and thereafter, performing dry etching on said workpiece through said mask to sever said workpiece along said projected dicing lines; wherein the step of cutting said workpiece includes the step of cutting said workpiece while supplying a cutting fluid containing an organic acid and an oxidizing agent to said workpiece.
