Summary: | A patterning device support (200), for example, a patterning device (202) or substrate support, can be configured to release internal stresses of a patterning device loaded thereon. The patterning device support can include a positive pressuring generating interface (206a, 206b) or an acoustic vibration generating interface (206a, 206b), or can be configured to oscillate while at least a portion of patterning device is decoupled from the patterning device support. A method of transferring a patterning device between a patterning device handling apparatus and a patterning device support configured to move the patterning device can include positioning the patterning device onto a surface of the patterning device support, and performing a process that releases internal stress of the patterning device. |
