Litho focus tilt
WebHigh NA systems provide better resolution capability but at the direct expense of focus latitude or “depth of focus”. The NA, resolution capability and focus latitude of a given exposure process are related by the Rayleigh criteria (named for British physicist Lord Rayleigh and often referred to as “Rayleigh’s Theorem” by optical lithographers).
