Publication number: US20210181458A1

Abstract:
A lens barrel capable of increasing the moving range of a lens includes: a lens retainer frame for holding a lens; a drive unit for driving the lens retainer frame along the optical axis direction; a first cylinder that holds the drive unit and has a cam follower; a second cylinder that has a cam groove for engaging the cam follower; and a bias part for biasing the first cylinder along the optical axis.

Publication number: US20200096872A1

Abstract:
Lithographic exposure tool and method for operating thereof are provided that includes modification of the tool (assessed based on the measurements of geometrical distortions caused, in the tool, by the exposure process and used to train the exposure tool) to ensure that such geometrical distortions are reduced for any chosen exposure process. The method includes processing first data (representing distortions caused by initial exposure run(s)) to estimate second data (representing distortions that would occur for another exposure run); and forming a modified exposure tool by changing at least one of a) a geometrical path or a path along which the workpiece stage is repositioned during the operation of the exposure tool; b) one or more of a presence, position, orientation, size and shape of an optical component of an optical projection sub-system of the optical system of the exposure tool; and c) a parameter of scanning synchronization of the exposure tool.

Publication number: US20190339479A1

Abstract:
A mirror assembly (32) for directing a beam (28) includes a base (450), and an optical element (454) that includes (i) a mirror (460), (ii) a stage (462) that retains the mirror (460), (iii) a mover assembly (464) that moves the stage (462) and the mirror (460) relative to the base (450), and (v) a thermally conductive medium (466) that is positioned between the stage (462) and the base (450) to transfer heat between the stage (462) and the base (450). The thermally conductive medium (466) has a thermal conductivity that is greater than the thermal conductivity of air. The thermally conductive medium (466) can include an ionic fluid or a liquid metal.
