摘要:
A method including mixing using a mixer a first component and a second component to form a liquid before supply to a space between the projection system and a substrate, measuring a property of the liquid using a measuring device and making the feedback available to a controller, based on the feedback, controlling with the controller a physical property of the liquid by controlling the amount of the first and/or second component used to form the liquid, supplying the liquid to the space between the projection system and the substrate, and projecting a patterned beam of radiation, using the projection system, through the liquid onto a target portion of the substrate.

摘要:
Systems and methods are used to modify a layer on a substrate that is used to form a pattern generator, so that light reflecting from the modified substrate has a trapezoidal or other custom profile. The layer is modified using various vapor deposition techniques in conjunction with moving or positioning the substrate a desired distance from a blocking device and/or at a desired rate or speed.

A diffraction element can be used in a system employing very short wavelengths of light, for example light in the nanometer range (e.g., about 100 nm to about 300 nm). The diffraction element is formed using a substrate (or any optical element) having high transmission characteristics in this wavelength range. For example, calcium fluoride or barium fluoride can be used. A layer of amorphous isotropic material, such as silicon dioxide or silica, is deposited on the substrate and patterned to allow for diffraction.

The present invention relates to an apparatus for polarizing an incident light beam. In embodiments, a tile wave plate assembly is provided. The tile wave plate includes a layered structure having a substrate plate and two layers of mosaic tiles. The layers of the apparatus are mechanically separated to form a controlled gap spacing. The mosaic tiles can be configured to form a pseudo or true zero order wave plate.
