    摘要: A method for optimizing imaging and process parameter settings in a lithographic pattern imaging and processing system. The method includes correlating the dimensions of a first set of at least one control pattern printed in a lithographic resist layer, measured at three or more locations on or within the pattern which correspond to differing dose, defocus and blur sensitivity. The method then includes measuring the dimensions on subsequent sets of control patterns, printed in a lithographic resist layer, at three or more locations on or within each pattern, of which a minimum of three locations match those measured in the first set, and determining the effective dose, defocus and blur values associated with forming the subsequent sets of control patterns by comparing the dimensions at the matching locations with the correlated dependencies.

    摘要: A method of forming an image in a photoresist layer. The method includes, providing a substrate; forming the photoresist layer over the substrate; forming a contamination gettering topcoat layer over the photoresist layer, the contamination gettering topcoat layer including one or more polymers and one or more cation complexing agents; exposing the photoresist layer to actinic radiation through a photomask having opaque and clear regions, the opaque regions blocking the actinic radiation and the clear regions being transparent to the actinic radiation, the actinic radiation changing the chemical composition of regions of the photoresist layer exposed to the radiation forming exposed and unexposed regions in the photoresist layer; and removing either the exposed regions of the photoresist layer or the unexposed regions of the photoresist layer. The contamination gettering topcoat layer includes one or more polymers, one or more cation complexing agents and a casting solvent.
