    摘要: Methods and apparatuses for controlling characteristics of radiation directed to a microlithographic workpiece are disclosed. An apparatus in accordance with one embodiment of the invention includes a source of radiation positioned to direct a radiation beam having an amplitude distribution, a phase distribution, and a polarization distribution, toward a workpiece. An adaptive structure can be positioned in a path of the radiation beam and can have a plurality of independently controllable and selectively radiation transmissible elements, each configured to change at least one of the amplitude distribution, the phase distribution and the polarization distribution of the radiation beam. A controller can be operatively coupled to the adaptive structure to direct the elements of the adaptive structure to change from one state to any of a plurality of available other states. Accordingly, the adaptive structure can provide radiation beams having a variety of continuously variable distributions for a variety of radiation beam characteristics.

    摘要: A structural shear panel for forming a floor panel for support by a vehicle frame is formed by a composite of top and bottom sheets and a core with a vacuum infused resin. The panel is mainly planar and terminates at its side edges at a portion which lies in a common plane and portions are provided which are deformed out of the generally planar shape to form depending or elevated sections. The structure is formed on a generally flat plate defining the planar panel portion with removable sections to define the depending and elevated sections. Edge pieces are attached to the plate to define the edges of the panel. Accessories are attached to the panel without compressing the core by a base plate of the accessory which is bolted to a bracket which has a backer plate and collar through a hole in the panel.

    摘要: A semiconductor pattern mask that might otherwise exhibit three-fold symmetry, which could give rise to distorted semiconductor features in the presence of three-leaf aberration in the optical system used to expose a semiconductor wafer through the mask, is altered to break up the three-fold symmetry without altering the semiconductor features that are formed. This accomplished by adding features to the mask that break up the symmetry. One way of achieving that result is to make the added features of “sub-resolution” size that do not produce features on the exposed wafer. Another way of achieving that result is to change existing features that do form structures in such a way (e.g., with optical elements) that changes the relative phase, amplitude or other characteristic of light transmitted through those features.

    摘要: The invention includes a method for placement of sidelobe inhibitors on a radiation-patterning tool. Elements of the tool are represented by design features in a modeling domain. The modeling domain is utilized to generate vectors spanning between edges of design features within a threshold spatial distance of one another. Locations of vector midpoints are identified. The locations are utilized in identifying areas where sidelobe overlap is likely. The areas are shifted from the modeling domain to a real domain, and in the real domain correspond to regions of the tool where sidelobe overlap is likely to occur. Sidelobe inhibitors are formed across at least some of the identified regions of the tool. The invention includes computer readable code that can enable a computer to determine locations for placement of the sidelobe inhibitors.
