文摘

Laser cutting of 75 µm glass substrate coated with multilayered films (i.e., OSR) was carried out. Different laser parameters was altered for optimizing the cutting process. Both linear and contour cutting profiles were successfully attempted. In-detail optical and scanning electron microscopy investigations were carried out to study cutting edge quality. Sheet resistance and surface property were measured locally prior and after cutting.
