发明名称 FOCUS CORRECTION IN LITHOGRAPHY TOOLS VIA LENS ABERRATION CONTROL
摘要 Aberration control capabilities of sophisticated lithography tools may be exploited in order to locally adapt the focal surface of the optical system. That is, higher order correction terms may be incorporated in the design of the local surface in addition to the conventionally used first order corrections, thereby enhancing uniformity of the lithography process and thus of corresponding microstructure devices.
