Diffractive lenses for vision correction are provided on a lens body having a first diffractive structure for splitting light into two or more diffractive orders to different focal distances or ranges, and a second diffractive structure, referred to as a multiorder diffractive (MOD) structure, for diffracting light at different wavelengths into a plurality of different diffractive orders to a common focal distance or range. In a bifocal application, the first and second diffractive structures in combination define the base power for distance vision correction and add power for near vision correction of the lens. The first and second diffractive structures may be combined on the same surface or located on different surfaces of the lens. The first diffractive structure may have blazed (i.e., sawtooth), sinusoidal, sinusoidal harmonic, square wave, or other shape profile. A sinusoidal harmonic diffractive structure is particularly useful in applications where smooth rather than sharp edges are desirable.

The present invention generally relates to a refurbished electrostatic chuck and a method of refurbishing a used electrostatic chuck. Initially, a predetermined amount of dielectric material is removed from the used electrostatic chuck to leave a base surface. Then, the base surface is roughened to enhance the adherence of new dielectric material thereto. The new dielectric material is then sprayed onto the roughened surface. A mask is then placed over the new dielectric material to aid in the formation of mesas upon which a substrate will sit during processing. A portion of the new dielectric layer is then removed to form new mesas. After removing the mask, edges of the mesas may be smoothed and the refurbished electrostatic chuck is ready to return to service after cleaning.

The optical assembly of a GDI instrument is configured to deviate or steer stray beams away from the pupil of the instrument's imaging device and / or to suppress stray beams. Stray beam deviation is optimized by selecting particular wedge and / or tilt configurations that achieve the desired stray beam deviation while avoiding or at least minimizing phase offset at the optimum metrology plane. Stray beam suppression can be achieved by providing the diffractive groove profile of the instrument's optical assembly with smooth edges. The resultant profile facilitates effective diffraction order management as well as a reduction in back reflection. The invention is particularly well-suited for use with a GDI instrument in which the optical assembly comprises first and second diffraction gratings. In this case, any average phase offset that remains after setting wedge and / or tilt can be eliminated by inserting a suitable compensating plate between the first and second diffraction gratings or between the second diffraction grating and the object.
