发明名称 Lithography apparatus having a dynamically variable illumination beam
摘要 A lithographic apparatus, e.g. using an electron beam, to expose a radiation sensitive layer on a substrate to the pattern on a mask comprising pattern areas and opaque supports. The apparatus uses a variable shaped beam at the edges of the pattern areas to provide a uniform exposure, while avoiding illumination of the opaque supports.
