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 holding table, and, thereafter, cutting the workpiece along the projected dicing lines with an annular cutting blade, thereby separating the layered bodies. The cutting blade has a plurality of through holes defined in an outer peripheral portion thereof that cuts into the workpiece and extending through the cutting blade from a face side to a reverse side thereof, but not open at an outer peripheral edge thereof. 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.
