Abstract:
A method for excising cells of a panel, comprising the steps of:focusing a laser beam on a surface of a panel, wherein the laser beam has a wavelength between about 500 nanometers and about 600 nanometers, and wherein the panel comprises a layered structure that includes a dielectric layer and a metal layer; and moving the panel relative to the laser beam in a geometric pattern, such that at least one cell of the panel is excised, wherein said moving comprises: moving the panel relative to the laser beam in a first direction along a first kerf having a first width between a first pair of adjacent cells of the panel; and moving the panel relative to the laser beam in a second direction along a second kerf having a second width between a second pair of adjacent cells of the panel, and wherein the first and second directions are about perpendicular to each other.
