A dynamic mask module is disclosed, which comprises a microcomputer
system, a mask pattern generator and a light source. The mask pattern
generator is disposed over a substrate and electrically connected to the
microcomputer system. The microcomputer system transmits an image signal
to the mask pattern generator. The light source is disposed over the mask
pattern generator to a photo-resist layer on the substrate. The mask
pattern generated by the dynamic mask module is a dynamic image and the
mask pattern can be changed on anytime. In addition, the manufacturing
cost can be and the manufacturing time can be reduced.
