Abstract
The disclosure relates to a method of laser processing a glass material, including: forming a plurality of perforations within the glass material along a cutting line, wherein the material comprises a first surface and a second surface opposing the first surface, wherein the perforation extends through a thickness of the material from the first surface to the second surface, and wherein a first crack is formed between adjacent perforations; applying water to the cutting line; and applying one of chemical or mechanical energy to the glass material at the cutting line to separate the material.

A method of laser processing a glass material, comprising:
- forming a plurality of perforations within the glass material along a cutting line,
- wherein the material comprises a first surface and a second surface opposing the first surface,
- wherein the perforation extends through a thickness of the material from the first surface to the second surface, and
- wherein a first crack is formed between adjacent perforations;
- applying water to the cutting line;
- and
- applying one of chemical or mechanical energy to the glass material at the cutting line to separate the material.
The method of laser processing a glass material, comprising:
- forming a plurality of perforations within the glass material along a cutting line within a first process chamber,
- wherein the material comprises a first surface and a second surface opposing the first surface,
- wherein the perforation extends through a thickness of the material from the first surface to the second surface, and
- wherein a first crack is formed between adjacent perforations;
- applying water to the cutting line within a second process chamber;
- and
- applying one of chemical or mechanical energy to the glass material at the cutting line within a third process chamber to separate the material.
