Abstract:
A laser processing method includes holding a single crystal silicon wafer as a workpiece, selecting a laser beam having a wavelength of 1950 nm or more in a transmission wavelength region to the single crystal silicon wafer, and applying the laser beam to the single crystal silicon wafer along a predetermined area with the focal point of the laser beam set inside the wafer, thereby forming a plurality of shield tunnels arranged along the predetermined area. Each shield tunnel is composed of a fine hole and an amorphous region formed around the fine hole for shielding the fine hole. The fine hole extends from a beam applied surface of the wafer where the laser beam is applied to the other surface opposite to the beam applied surface.

Claim (Index 3):
A laser processing method using a laser processing apparatus including a chuck table for holding a workpiece and a laser beam applying unit including focusing means having a focusing lens for applying a laser beam to said workpiece held on said chuck table to thereby process said workpiece, said laser processing method comprising:\n a single crystal silicon wafer selecting step of selecting a single crystal silicon wafer as said workpiece; a laser beam selecting step of selecting a pulsed laser beam having a wavelength of 1950 nm or more in a transmission wavelength region to said single crystal silicon wafer as said laser beam; and a shield tunnel forming step of applying said pulsed laser beam to said single crystal silicon wafer along a predetermined area in the condition where the focal point of said pulsed laser beam is set inside said single crystal silicon wafer, thereby forming a plurality of shield tunnels arranged along said predetermined area, each shield tunnel being composed of a fine hole and an amorphous region formed around said fine hole for shielding said fine hole, said fine hole extending from a beam applied surface of said single crystal silicon wafer where said pulsed laser beam is applied to the other surface opposite to said beam applied surface.
