Abstract
PURPOSE: To prevent deformation and fusion-fixing of the stage due to heat of laser beam by forming a relief groove in a wafer and by performing scribe processing on a transparent stage from the opposite side.
CONSTITUTION: For the purpose of preventing deformation of processed stage (j) and fusion-fixing between the wafer and processed stage (j) due to heat of laser beam (e), stage (j) is made transparent to permeate laser beam (e). In case of complete clipping, relief groove (i) is opened to the clipped position of the wafer itself for the purpose of preventing the clipped position of the wafer from contact with the processed stage directly.
