A mirror is comprised of a reflective film including a flexible polymer with a reflective coating, at least one magnet attached to the reflective film, a motor configured to rotate the reflective film wherein the reflective film is secured to the motor, and at least one electromagnet configured to receive an applied voltage. The mirror further comprises a first flexible support layer to increase the rigidity of the reflective film during curvature change and a second rigid support layer to prevent the reflective film, first support layer, and at least one magnet from contacting the at least one electromagnet.

An operating method of an extreme ultraviolet (EUV) lithography device includes defining a target image to render an illumination system, assigning priorities to respective positions of facets of a pupil facet mirror corresponding to the target image, assigning a mirror according to the assigned priorities using linear programming, generating the illumination system by selecting one of the facets of the pupil facet mirror based on a symmetry criterion, and converting mirror assignment information and source map information corresponding to the selected facet into a form recognizable by an EUV scanner.

The present disclosure generally pertains to lightweight adaptive metal cooled mirrors and methods of producing the same. The metal mirror surface is integrated with and supported by metal channels which are physically incorporated into the mirror surface through an additive manufacturing process. These channels are nominally conformal with the desired mirror surface shape. A liquid or gaseous coolant may be directed through some or all of the channels to cool the mirror surface. The mirrors are produced through an additive manufacturing process which allows for the creation of a unitary optical mirror containing finely spaced channels.
