摘要:
A method and system are used to modify pattern data obtained in relation to a pattern on a static patterning device. It is suggested that, in an example when a maskless lithography tool is used, continuous OPC-enhanced features used for maskless lithography rasterization should include a variation in local amplitude and phase transmittance that matches modulation capabilities of a patterning device being used. The modified pattern data is used by a dynamic patterning device to pattern impinging light, which is then projected onto an object. The system and method comprise using a pattern data generating device, a modification device, a dynamic pattern generator, and a projection system. The pattern data generating device generates pattern data corresponding to a pattern on a static patterning device. The modification device receives the pattern data and modifies the pattern data using characteristics of a type of the dynamic pattern generator being used. The dynamic pattern generator receives the modified patterned data and uses the modified pattern data to pattern the beam of radiation. The projection system projects the patterned beam onto the object.
摘要:
A method of imaging radiation from an object on a detection device. The method includes directing a beam of coherent radiation to the object, scanning the beam of radiation over an angle in or out of a plane of incidence relative to the object, and imaging scattered radiation from the object on the detection device.
摘要:
A method of transferring an image of a pattern layout onto a surface of a substrate including selecting a first illumination profile for a first area of the pattern layout and a second illumination profile for a second area of the pattern layout; switching illumination profile during transfer of the image of the pattern layout such that the first area of the pattern layout is illuminated with the first illumination profile and the second area is illuminated with the second illumination profile; and projecting an image of the illuminated first and second areas onto the surface of the substrate.

A lithographic apparatus for maskless EUV applications includes an illumination system constructed and arranged to condition a radiation beam and to supply the conditioned radiation beam to a spatial light modulator, a substrate table constructed and arranged to hold a substrate, and a projection system constructed and arranged to project the conditioned radiation beam onto a target portion of the substrate. The illumination system includes a field facet mirror constructed and arranged to define a field of the conditioned radiation beam. The field facet mirror is constructed and arranged to optically match a source of radiation and the illumination system.
摘要:
The invention relates to a method and device of inspecting contamination particles on an object comprising a patterned structure. The device includes a radiation system for directing a radiation beam to the object. The object is configured to scatter the beam. The device also includes an optical system arranged to receive scattered radiation from the object, and a filter provided in the optical system. The filter is associated with the patterned structure so as to filter out radiation from the scattered radiation. The device also includes a detector arranged to detect a fraction of radiation that is transmitted by the filter. Accordingly, contamination particles may be detected quickly and accurately.
摘要:
A system and method are used to direct a radiation beam to illuminate non-perpendicularly a patterning array of individually controllable elements used for patterning the radiation beam. The individually controllable elements can change a telecentricity of the radiation beam. Projection of the radiation beam onto the individually controllable elements can be by a concave mirror or use a folding mirror placed in an object field of the individually controllable elements. Alternatively, the individually controllable elements can change the optical axis of the radiation beam.

Lithographic apparatus using an array of individually controllable elements in which a fraction of the intensity of the beam of radiation patterned by the array of individually controllable elements is diverted to an image sensor for verifying the quality of the image generated.
摘要:
A spatial light modulator used to pattern a radiation beam comprises an array of pixels disposed on a support. Each pixel has a light modulating element for modulating the radiation beam and a control circuit that positions the light modulating elements according to a desired pattern. The control circuit is disposed on the opposite side of the support than the light modulating elements. The control circuit comprises at least one of a digital to analog converter, an analog to digital converter, an optical fiber input, and a processor.
