摘要:
A lithographic method includes patterning a beam of radiation with a patterning device. The patterning device includes at least two image patterning portions and at least two metrology mark patterning portions. The method also includes projecting at least two image portions of the patterned beam of radiation sequentially onto target portions of a substrate such that the projected image portions are substantially adjacent to each other on the substrate and collectively form a composite image on the substrate. The method also includes projecting a metrology mark onto the substrate outside of the area of the composite image at the same time as projecting each of at least two of the image portions, and measuring the alignment of the metrology marks to determine the relative positions of the at least two image portions.
摘要:
Provided is a radiation distribution system for distributing the radiation from an illumination system to two or more patterning means, each for patterning beams of radiation, which are subsequently projected onto a substrate.
摘要:
An optical position assessment apparatus and method has an illumination system that supplies an alignment beam of radiation, and positional data is derived from reflections of the alignment beam. A substrate is supported on a substrate table and a projection system is used to project the alignment beam onto a target portion of the substrate. A positioning system causes relative movement between the substrate and the projection system. An array of lenses is arranged such that each lens in the array focuses a respective portion of the alignment beam onto a respective part of the target portion. An array of detectors is arranged such that each detector in the array detects light reflected from the substrate through a respective lens in the array and provides an output representative of the intensity of light reflected to it from the substrate through the respective lens. A processor is connected to the outputs of the detectors for deriving data representing the position of the lens array relative to the substrate from the outputs of the detectors.
