    摘要: A method for cutting a semiconductor wafer by generating a crack within the wafer, and a system thereof, are provided. The method comprises irradiating a laser beam towards a surface of the wafer and converging the laser beam to form a focal point so that a focal volume defined by the focal point and a boundary of the laser beam within the wafer is formed. Energy encompassed within the focal volume causes the wafer located at the periphery of the focal volume to contract faster than the wafer located within the focal volume, thereby generating a crack within the wafer.

    摘要: 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.

    摘要: A method of high speed cutting of non-metallic materials (14), preferably glass and laminated glass, is described. In the inventive method a concentrated microwave radiation (1) with appropriate frequency and power density is chosen so as to accomplish heating of at least one selected area (2) of the body at the required separating propagation path (3) to required temperature in a selected short time while ensuring that this temperature is large enough to create a thermal stress (6) through the thickness of the selected area that results in the separating of the body material. In one embodiment of the invention a method of high speed cutting laminated glass is described wherein concentrated microwave radiation is used for delaminating adhesive film before the step of separating the glass body.

    摘要: The present invention relates to a process for laser scoring of flat glass sheets. The process comprises manipulating a laser beam having a substantially Gaussian intensity profile to produce an elongated heating zone on the glass sheet to be scored, the elongated heating zone having a central portion with a lower temperature than a temperature of an outer portion of the heating zone. An initial crack is made in the glass sheet, the elongated heating zone is traversed across the glass sheet coincident with the initial crack, and the heated glass is thermally shocked by directing a cooled liquid against the heated glass, thus propagating the crack. The scored glass sheet may thereafter be broken by applying bending techniques as are known in the art.
