METHOD FOR SEPARATING A SHEET OF BRITTLE MATERIAL |
摘要 |
<p>A method for separating sheet of brittle material having a thickness equal to or less than about 1 mm is disclosed. Once an initial flaw or crack is produced, a full body crack can be propagated across a dimension of the brittle material with a laser beam that is substantially absorbed proximate the surface of the sheet to produce sub-sheets. In some embodiments, only a single pass of the laser beam over a surface of the sheet is necessary to separate the sheet. In other embodiments a plurality of passes may be used. Sub-sheets can be further processed into electronic devices by depositing thin film materials on the sub-piece.</p> |
