摘要:
A maskless lithography system has a patterning array assembly formed by a plurality of patterning arrays, each patterning array having a substrate. Each patterning array has a plurality of individually controllable elements to endow an incoming radiation beam with a patterned cross-section. To reduce the global unflatness of the patterning array assembly that is oriented in a first plane, the position of at least one substrate of a patterning array is adjusted to a second orientation. Reduction of the global unflatness of the patterning array assembly reduces a telecentricity error without introducing additional error into the maskless lithography system.
摘要:
One or more patterning arrays are mounted to a mounting plate via height adjustment structures that enable the flatness of the active surfaces of the patterning arrays to be controlled. The height adjustment structures may comprise an array of piezoelectric actuators or screws. Alternatively, the backside of the patterning means may be polished to optical flatness and bonded by crystal bonding to an optically flat surface of a rigid mounting body.

A system and method are used to allow for compensation of a thermal output of an array of individually controllable elements. This can be done by inputting control signals to the array when it is not being used to pattern a projection beam in order to maintain the temperature of the array. A heating element can be provided to maintain the temperature of the array. A thermal reservoir can be provided to maintain the temperature of the array or a cooling element can be provided to reduce the temperature of the array during use.

摘要:
A lithographic apparatus, a device manufacturing method, and a projection element for use in a lithographic apparatus are disclosed. The lithographic apparatus has a radiation system for providing a pulsed beam of radiation, a patterning device for imparting the beam with a pattern to form a patterned radiation beam, and a projection system having a projection element for projecting the patterned beam onto a target portion of a substrate. The apparatus further comprises an actuator for moving the projection element for shifting the patterned beam that is projected onto the substrate during at least one pulse of the radiation system. This can be done to compensate for a positional error between a substrate table holding the substrate and an aerial image of the projection system. The positional error could occur due to mechanical vibrations in the frame system of the lithographic apparatus.

An assembly includes a first element having a predetermined functionality that is to be positioned with respect to a second element. The elements are arranged in a spaced relationship on a support frame. The support frame is provided with an interface surface formed on or in the support frame for receiving the first element. The interface surface determines the position of the first element with respect to the second element, and is configured in accordance with the predetermined functionality so that the first element is positionable with respect to the second element with at least three degrees of freedom.
