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 2):
The laser processing apparatus according to  claim 1 , wherein the numerical aperture of said focusing lens is set so that the value obtained by dividing the numerical aperture of said focusing lens by the refractive index of single crystal silicon falls within the range of 0.05 to 0.2.
