Abstract:
A mask for making a polysilicon structure includes a transmitting area that transmits light and a blocking area that has a metal layer and a semiconductor layer deposited in an alternating manner at least once. The blocking area blocks light. The mask is subject to less thermal stress from the light (e.g., a laser beam) and therefore has a longer life span compared to a conventional mask.
