Laser mask and crystallization method using the same |
摘要 |
A laser mask includes a mask pattern with edges having inverted shapes to alleviate the effects of diffraction of laser beams to reduce overlap regions such that crystallization characteristics are improved. The laser mask includes a mask pattern that includes transmitting regions and a blocking region. The edges of the mask have shapes inverted to the shapes of the edges of a silicon thin film crystallized by the pattern.
