Abstract:
A method of controlling reticle masking blade positioning to minimize the impact on critical dimension uniformity includes determining a target location of a reticle masking blade relative to a reflective reticle and positioning the reticle masking blade at the target location. A position of the reticle masking blade is monitored during an imaging operation. The position of the reticle masking blade is compared with the target location and the position of the reticle masking blade is adjusted if the position of the reticle masking blade is outside a tolerance of the target location.

Claim (Index 16):
An extreme ultraviolet lithography tool, comprising:\n an extreme ultraviolet radiation source; a moveable stage for supporting a photoresist coated substrate; one or more reticle masking blades located between the extreme ultraviolet radiation source and a reflective reticle support stage; a position sensor configured to monitor a position of the one or more reticle masking blades during a selective photoresist exposing operation; one or more actuators configured to adjust the position of the one or more reticle masking blades if the one or more reticle masking blades are outside a set tolerance range; and a controller configured to determine whether the one or more reticle masking blades are located within the set tolerance range, and configured to control the actuators.
