Abstract: A method utilizes a dynamically controllable optical element that receives an electrical field, which changes an index of refraction in at least one direction within the optical element. The change in index of refraction imparts a change to a beam of radiation passing through the optical element. The electric field is controlled by a feedback/control signal from a feedback system that includes a detector positioned proximate an image plane in the system. The optical element can be positioned in various places within the system depending on what light characteristics need to be adjusted, for example after an illumination system or after a light patterning system. In this manner, the optical element, under control of the dynamic electric field, can dynamically change its propagation characteristics to dynamically change either a beam of illumination from the illumination system or a patterned beam of radiation from the patterning system, such that they exhibit desired light characteristics.

Abstract: A system and method utilize an optical element that receives an electrical field, which changes an index of refraction in at least one direction within the optical element. The change in index of refraction imparts a change to a beam of radiation passing through the optical element. A material used to form the optical element exhibits characteristics, such that wavelengths of the beam of radiation above about 155 nanometers are transmitted through the optical element with little or not absorption or attenuation.

Abstract: Electromagnetic energy is emitted from an illumination source of a lithography device. A portion of the emitted electromagnetic energy passes through an illumination optics module. The illumination optics module includes a one-dimensional optical transform element having a pupil plane. An aperture device having an adjustable aperture is located proximate to the pupil plane so that a portion of the electromagnetic energy received by the one-dimensional optical transform element passes through the aperture of the aperture device. The angular distribution of the electromagnetic energy passing through the illumination optics module is adjusted as a function of illumination field position using the aperture device, thereby improving line width control in the lithography device.

Abstract: A system and method for improving line width control in a lithography device are presented. Electromagnetic energy is emitted from an illumination source and passed through illumination optics. The illumination optics include a partial coherence adjuster having a first and second optical element. The first optical element is used for changing the partial coherence of incident electromagnetic energy in a predetermined manner to compensate for horizontal and vertical line biases of the lithography device. The second optical element is used for changing the angular distribution of electromagnetic energy incident upon the first optical element. Together, the two optical elements are used to vary the partial coherence of the electromagnetic energy emitted by the illumination source, as a function of illumination field position, and improve line width control. Adjustment of the second optical element allows for correction of time-dependant line width variances.
