In the fabrication of touch panel modules, a number of complex process steps are required, of which thin-film patterning is the most important and expensive step in the production. While the conventional fabrication of Indium Tin Oxide (ITO) and silver (Ag) pattern is based on a complex and expensive photolithographic process, laser scribing offers a dry, chemical waste free, high throughput process that is widely used today in flat panel and touch panel display device manufacturing. Moreover, laser technology enables economic and market viability by meeting the need for continuous decrease in weight and size of the flat and touch panel devices.
