Geometric compensation method for charged particle beam irradiation

摘要

A charged particle beam method for irradiating an array of sub-regions within an areal region within a substrate with a series of shots of a charged particle beam provides that a sequencing of irradiation of the array of sub-regions is geometrically determined such as to minimize charged particle beam deflection when irradiating the series of sub-regions with the series of shots of the charged particle beam. Due to the geometric determination which provides the minimized charged particle beam deflection, the charged particle beam method has enhanced accuracy.
