Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive material capable of forming a material having a low outgassing ratio, a low modulus of elasticity, and a low Tg. SOLUTION: A composition substantially comprises a mixture, a blend or a reaction product formed out of a photo- or electron beam-curing material component, a photoinitiator/photosensitizer component, and, if necessary, a viscosity controlling component, and further, if necessary, an inert filler, wherein the photo- or electron beam-curing material component contains a hydrocarbon-based rubbery material which has completely or substantially completely no carbon-carbon double bond nor triple bond and is completely or substantially completely hydrogenated as a base material, the photoinitiator/photosensitizer component has substantially no volatility at room temperature and forms a photoreaction product having the volatility at the minimum level or not at all at the room temperature after exposed to chemical rays, the viscosity controlling component is solely polymerizable or copolymerizable with the photo- or electron beam-curing material component.

Abstract:
Die vorliegende Anmeldung ist gerichtet auf ein Verfahren zum Bestimmen der Beschaffenheit der Reinheit eines optischen Bauelements bevor eine Beschichtung auf der Oberfläche aufgebracht wird. Das Verfahren ist insbesondere für optische Bauteile und Bauelemente anwendbar, die für Verwendungen in den DUV-(tiefen Ultraviolett – deep ultraviolet) und EUV-(extremen Ultraviolett – extreme ultraviolet) Wellenlängenbereichen vorgesehen sind. Die Anmeldung kombiniert ein Reinigungsverfahren mit einer Verunreinigungs-Messtechnik unter Verwendung eines Spektrometers, um ein Verfahren bereitzustellen, das die Beschaffenheit der Reinheit der Bauelementoberfläche durch Messen des Fluoreszenzspektrums der Optik und Vergleichen des gemessenen Werts mit einer Standard- oder Referenz-Optik einer bekannten akzeptablen Reinheit bestimmt. Die Anmeldung ist ferner gerichtet auf eine Optik mit einer ausgewählten Beschichtung drauf, die gemäß dem hierin beschriebenen Verfahren gebildet ist.
Abstract:
A light pulse conditioning.apparatus (30) has first and second curved reflective surfaces (12a, 12b) that share a common focus and a light-redirecting element (16) disposed between the first and second curved reflective surfaces to redirect a portion of an incident light beam (14) toward the second curved reflective surface (12b) as a delayed beam portion. A beam-shifting compensating element (24) is disposed between the first curved reflective surface (12a) and the light-redirecting element (16), for shifting the optical path of the delayed beam portion as it returns toward the light-redirecting element (16). Furthermore, the light conditioning apparatus (30) may have a measurement device (52) using a sensor (54) to detect the energy level of the light beam (14) from the pulset radiation source (38) and providing a signal to a controller (56) for a modulator element (34) of a modulator assembly (32). When the pulse power exceeds a value, the control loop (50) energizes the modulator element (34) to provide some level of attenuation.
Abstract:
An apparatus for providing a pulsed radiation beam has a radiation source providing a pulsed radiation beam at a constant pulse repetition frequency. A beam deflector in the path of the pulsed radiation beam is actuable to redirect the pulsed radiation beam cyclically towards each of a plurality of beam intensity modulators in turn. A beam recombiner combines modulated light from each of the plurality of beam intensity modulators in order to form the modulated pulsed radiation beam at the constant pulse repetition frequency.
Abstract:
Disclosed are photo or electron beam curable polymerizable compositions, and preparation thereof and devices containing such cured material. The composition contains completely or substantially completely hydrogenated hydrocarbon-based material completely free or substantially free of carbon-carbon double and triple bonds containing photo or electron beam curable terminal or pendant groups, low-outgassing photoinitiators, an optional viscosity adjustment component and an optional filler. The composition is visible light, UV or electron beam curable. It cures into a low-modulus, low outgassing polymer material. The composition can be used as an adhesive, sealant or lens potting material. It is ideal for use in lithographic tools and other optical devices involving deep or vacuum ultraviolet radiations, in particular, as lens potting materials for 248 nm, 193 nm and 157 nm lithographic tools, as well as other optical devices involving using high fluence irradiation.
