    摘要: The technology disclosed relates to methods and devices that compensate for displacements in a pattern or deformations of workpiece. In particular, that relates to using timing to compensate for displacements along a first axis along the scanning direction while using resampling, interpolation or a similar method to compensate for displacements along a second axis that is substantially orthogonal to the first axis. The scanning direction may be an actual direction of movement of the scanning head or it may be a direction perpendicular to an orientation of an image projected onto a workpiece.

    摘要: A novel silicon micromirror structure for improving image fidelity in laser pattern generators is presented. In some embodiments, the micromirror is formed from monocrystalline silicon. Analytical- and finite element analysis of the structure as well as an outline of a fabrication scheme to realize the structure are given. The spring constant of the micromirror structure can be designed independently of the stiffness of the mirror-surface. This makes it possible to design a mirror with very good planarity, resistance to sagging during actuation, and it reduces influence from stress in reflectivity-increasing multilayer coatings.

    摘要: In a method for measuring lithographic features on a surface with an optical system, a laser beam is scanned over lithographic features on the surface and the laser beam is reflected or transmitted. An image of the lithographic features is formed by the reflected or transmitted laser beam. The image is filtered using a filter, which is an inverse convolution based on a kernel representing the optical system. The filtering provides a threshold that is equal for all line widths and provides the same relative difference from the nominal critical dimension for all line widths. The surface is a wafer or a work piece.

    摘要: A method, apparatus for and a device manufactured by the same, for printing a microlithographic pattern with high fidelity and resolution using simultaneously optimized illuminator and pupil filters having semi-continuous transmission profiles. The optimization can be further improved if the illuminator and pupil filters are polarization selective. The optimization method becomes a linear programming problem and uses a set of relevant features in the merit function. With a suitably chosen merit function and a representative feature set both neutral printing without long-range proximity effects and good resolution of small features can be achieved. With only short-range proximity effects OPC correction is simple and can be done in real time using a perturbation method.

The electromagnetic radiation source may emit electromagnetic radiation to create a pattern on a workpiece.
