Patent number: 9468996Abstract: A method of repairing a substrate that may prevent a metal layer from being corroded. A substrate including a metal layer and an insulating layer on the metal layer is first provided. Then, a laser beam having a wavelength range having a high transmittance with respect to the insulating layer is irradiated to selectively remove a portion of the metal layer. Also, a first laser beam is irradiated to remove a portion of the metal layer and a portion of the insulating layer, and then a second laser beam is irradiated onto side surfaces of the exposed insulating layer to melt the insulating layer, thereby forming a corrosion preventing layer covering the metal layer.Type: GrantFiled: August 2, 2013Date of Patent: October 18, 2016Assignee: Samsung Display Co., Ltd.Inventor: Sung Bae Ju
