Title:
【発明の名称】Nd:YAGレーザを使用するガラス上へのレーザスクライビング
Document Type and Number:
Japanese Patent JP3001816
Kind Code:
B2
Abstract:
A method and an apparatus for inscribing a pattern into a surface (18a) of a substrate (18), such as a sheet of glass, are disclosed. The method includes the steps of providing a Nd:YAG laser (12) having a characteristic output wavelength at 1,06 micrometers, providing a glass substrate (18) that is substantially transparent to the characteristic output wavelength and applying a layer (16) of material, such as a layer of tape, to the surface (18a). The layer (16) of material is selected so as to strongly absorb the characteristic output wavelength. A next step focusses (14) an output (12a) of the laser (12) into a spot (12c) at or near to an interface between the layer (16) of material and the surface (18a) of the substrate (18). A further step translates (20) the surface (18a) relative to the spot (12c). The layer (16) of material absorbs the output of the laser (12) and is heated thereby to a temperature sufficient for inscribing the surface (18a) underlying the spot (12c). That is, the layer (16) of material enables the laser (12) to build a plasma state adjacent to the surface (18a) of the substrate (18), which in turn scribes the surface (18a) of the substrate (18).
