MANUFACTURING METHOD FOR SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD FOR DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a highly reliable semiconductor device by improving the utilization efficiency of material and by simplifying the manufacturing process.

SOLUTION: The manufacturing method comprises the steps of forming a conductive layer on a substrate, forming a light-transmitting layer on the conductive layer, delivering a femtosecond laser onto the light-transmitting layer, and selectively removing the conductive layer and the light-transmitting layer. The conductive layer and the light-transmitting layer may be removed so that an end of the conductive layer is located inside as compared with an end of the light-transmitting layer. Before the delivery of the femtosecond laser, a surface of the light-transmitting layer may be subjected to liquid repellent treatment.
