  • Apparatus with double laser beams for cutting two bonded glass substrates and method thereof
    Patent number: 6576870
    Abstract: An apparatus for cutting a laminated structure formed by two bonded glass substrates comprises a worktable, and at least one laser generator. The worktable has at least one liner opening, wherein the laminated structure is placed on the worktable and a predetermined scribing line on the laminated structure is aligned to the liner opening. The laser generator generates a first laser beam over the worktable and a second laser beam under the worktable. The first laser beam irradiates the predetermined scribing line on the upper glass substrate of the laminated structure. The second laser beam passes through the liner opening and irradiates the predetermined scribing line on the lower glass substrate of the laminated structure.
