Method of making a lithography mask |
摘要 |
A method of making a lithography mask with a stress-relief treatment is disclosed. The method includes providing a substrate and depositing an opaque layer on the substrate. The opaque layer is patterned to form a patterned mask. A stress-relief treatment is applied to the patterned mask by using an radiation exposure. |
