摘要:
A metrology tool is arranged to measure a parameter of a substrate that has been provided with a pattern in a lithographic apparatus. The metrology tool includes a base frame, a substrate table constructed and arranged to hold the substrate, a sensor constructed and arranged to measure a parameter of the substrate, a displacement system configured to displace the substrate table or the sensor with respect to the other in a first direction, a balance mass, and a bearing configured to movably support the first balance mass so as to be substantially free to translate in a direction opposite of the first direction in order to counteract a displacement of the substrate table or sensor in the first direction.

A method and system are provided for printing a pattern on a photosensitive surface using a maskless lithography system including a spatial light modulator (SLM). The method includes defining two or more exposure areas within a predetermined region of the surface, each area corresponding to selected pixels of the SLM. An overlap region is formed between the two or more exposure areas, the overlapping region being defined by respective overlapping edges of the exposure areas, the overlapping edges corresponding to overlapping pairs of the selected pixels from each area. The pixels within each pair are alternately activated such that only one of the pixels within the pair is used to produce the pattern.

An imprint lithography apparatus is disclosed that has a first array of template holders, a second array of template holders, and a substrate table arranged to support a substrate to be imprinted, wherein the first array of template holders is arranged to hold an array of imprint templates that can be used to imprint a first array of patterns onto the substrate, and the second array of template holders is arranged hold an array of imprint templates that can be used to imprint a second array of patterns onto the substrate, the patterns imprinted by the second array being interspersed between the patterns imprinted by the first array.
摘要:
Grayscale Optical Proximity Correction device features are added to a mask pattern by convoluting the device features with a two-dimensional correction kernel or two one-dimensional correction kernels to generate grayscale OPC features. The resulting pattern may be used in a projection lithography apparatus having a programmable patterning means that is adapted to generate three or more intensity levels. An iterative process of simulating an aerial image that would be produced by the pattern, comparing the simulation to the desired pattern, and adjusting the OPC features may be used to generate an optimum pattern for projection
摘要:
A lithographic projection apparatus comprises a microlens array for generating a plurality of source images in a two-dimensional array, a programmable patterning means having a plurality of addressable elements acting as shutters for the source images and a projection subsystem for projecting a n image of the array of source images onto a substrate. A greater working distance can thereby be obtained

A system and method are provided including different moveable lenses within a projection system that can be placed in the path of a radiation beam to change a magnification of the projection system. By changing the magnification of the projection system an area of a substrate exposed per pixel can be adjusted, and a throughput of the system optimized.
摘要:
A system and method are used for pulse to pulse dose control in an illumination system, used, for example, in a lithography or a maskless lithography machine. The system and method can be used to decrease effective laser pulse-to-pulse variability in lithographic lasers, allowing adequate dose control using a minimum number of pulses (e.g. as little as one pulse).
