Abstract: A method and system for repairing photomasks is disclosed. A scanning electron microscope (SEM) is used to identify, measure, and correct defects. The SEM is operated in multiple modes, including a measuring mode and a repair mode. The repair mode is of higher landing energy and exposure time than the measuring mode, and induces shrinkage in the photoresist to correct various features, such as vias that are too small.

Abstract: A charged beam apparatus, such as an electron microscopy apparatus, and a method for determining an aerial dimensional map of a charged beam within the charged beam apparatus, each use a test structure that includes a feature located upon a substrate. One of the feature and the substrate is conductive and the other of the feature and the structure is non conductive. The charged beam within the charged beam apparatus is scanned in a plurality of non-parallel linear directions with respect to the substrate and the feature to provide a corresponding plurality of current versus position response curves from which may be determined the aerial dimensional map of the charged beam within the charged beam apparatus.

Abstract: A method for forming a patterned target layer over a substrate uses a blanket target layer located over the substrate and a patterned mask layer located over the blanket target layer At least one mask layer pattern wit the patterned mask layer is treated with a charged particle beam to provide a dimensionally changed mask layer pattern within a dimensionally changed mask. The dimensionally changed mask is used as an etch mask when etching the blanket target layer to form the patterned target layer.
