Abstract: An apparatus for compensating light exposure on different, subsequently irradiated target areas (11, 12) in a photosensitive medium (2) on a semiconductor wafer (1). In order to improve exposure dose uniformity the apparatus comprises a mask filter (9) with a plurality of oblong transparent (31) and oblong opaque elements (32; 41) inserted between a light source (3) and said photosensitive medium (2) so that light (4) traverses through said plurality of transparent elements (31) to expose the photosensitive medium.

Since the polishing rate is reduced, endpointing is enhanced. The concentration is altered by adding further oxidizing or reducing agents.

Abstract: A lithographic tool can be adjusted by inspecting wafer images of an defect inspection tool and correlating the wafer images with images from a reference library in a database. Each reference image in the database corresponds to an initially measured amount of miss adjustment of lithographic tool parameters. The lithographic tool is adjusted automatically according to the reference image that is found to have the greatest resemblance to the wafer image. Time for adjusting is saved, operator staff needed is reduced, and objective determination criteria provide high wafer quality and yield.
