Abstract:
A reflector for an ultraviolet lamp can be used in a substrate processing apparatus. The reflector comprises a centrally positioned longitudinal strip and first and second side reflectors to form a parabolic-type surface. The longitudinal strip and first and second side reflectors have curved reflective surfaces with dichroic coatings and the longitudinal strip comprises a plurality of through holes to direct a coolant gas toward the ultraviolet lamp. A chamber that uses an ultraviolet lamp module with the reflector, and a method of ultraviolet treatment are also described.
Abstract:
An optical component includes an optical element, a mount for the optical element, and a temperature control device configured to control a temperature of a part of the mount based on at least one parameter selected from the group consisting of a coefficient of expansion of a substrate of the optical element, and a coefficient of expansion of a material of the mount.
Abstract:
An illumination system for a microlithography projection exposure apparatus generally includes an optical element formed of a plurality of facet elements. The facet elements are arranged such that, for each facet element, a proportion of the side surfaces of the facet element is at a certain distance from the side surfaces of all the other facet elements. This gives rise to interspaces between the facet elements which are not used optically. The interspaces can be used for simpler mounting of the facet elements or for fitting mechanical components, such as actuators. A collector is used to efficiently illuminate such an optical element. The collector includes a plurality of segments that are in part non-continuous. Alternatively, however, continuous segments with a bend are also possible.

A reflector for an ultraviolet lamp can be used in a substrate processing apparatus. The reflector comprises a longitudinal strip extending the length of the ultraviolet lamp. The longitudinal strip has a curved reflective surface and comprises a plurality of through holes to direct a coolant gas toward the ultraviolet lamp. A chamber that uses an ultraviolet lamp module with the reflector, and a method of ultraviolet treatment are also described.
Abstract:
An apparatus and method for EUV light production is disclosed which may comprise a laser produced plasma (“LPP”) extreme ultraviolet (“EUV”) light source control system comprising a target delivery system adapted to deliver moving plasma initiation targets and an EUV light collection optic having a ibeus defining a desired plasma initiation site, comprising; a target tracking and feedback system comprising: at least one imaging device providing as an output an image of a target stream track, wherein the target stream track results from the imaging speed of the camera being too slow to image individual plasma formation targets forming the target stream imaged as the target stream track; a stream track error detector detecting an error in the position of the target stream track in at least one axis genemily perpendicular to the target stream track from a desired stream truck intersecting the desired plasma initiation site.
Abstract:
To provide an optical thin film structure capable of efficiently dissipating heat in an optical thin film which is generated upon irradiating a surface of an X-ray mirror made up of the optical thin film with an X-ray. The optical thin film having an isotope purity higher than a natural isotope abundance ratio is formed on a mirror to increase heat conductivity of the optical thin film itself and quickly dissipate heat accumulated in the thin film to the outside of an optical system. Consequently, the mirror having high reflectively can be obtained, in which a fine structure of the optical thin film is by no means broken.
Abstract:
An apparatus and method is described which may comprise a plasma produced extreme ultraviolet (“EUV”) light source multilayer collector which may comprise a plasma formation chamber; a shell within the plasma formation chamber in the form of a collector shape having a focus; the shell having a sufficient size and thermal mass to carry operating heat away from the multilayer reflector and to radiate the heat from the surface of the shell on a side of the shell opposite from the focus. The material of the shell may comprise a material selected from a group which may comprise silicon carbide, silicon, Zerodur or ULE glass, aluminum, beryllium, molybdenum, copper and nickel. The apparatus and method may comprise at least one radiative heater directed at the shell to maintain the steady state temperature of the shell within a selected range of operating temperatures.
Abstract:
There is provided a collector for illumination systems for light having a wavelength ≦193 nm comprising. The collector includes (a) a first mirror shell adjacent to, and positioned inside of, a second mirror shell around a common axis of rotation, in which the first and second mirror shells are rotationally symmetric, and (b) a component in a region between the first and second mirror shells. The collector is for receiving the light from a light source via an object-side aperture and for illuminating an area in an image-side plane, and the region is not used by the light.
