Abstract:
A processing method for processing a plate-shaped workpiece having a division line on the front side and a multilayer member containing metal formed on the back side is provided. The processing method includes a holding step of holding the front side of the workpiece on a holding table in the condition where the multilayer member formed on the back side of the workpiece is exposed, a cutting step of cutting the workpiece along the division line by using a cutting blade after performing the holding step, thereby forming a cut groove dividing the multilayer member, and a laser processing step of applying a laser beam to the workpiece along the cut groove after performing the cutting step. The cutting step includes the step of supplying a cutting fluid containing an organic acid and an oxidizing agent to the workpiece.

Claim (Index 2):
The processing method according to  claim 1 , wherein said laser processing step includes the step of applying a laser beam having an absorption wavelength to said workpiece along said cut groove to thereby fully cut said workpiece along said cut groove.
