    Abstract: In EUV lithography apparatus (10), it is proposed, in order to lengthen the lifetime of contamination- sensitive components, to arrange them in a protection module. The protection module comprises a housing (23-29) having at least one opening (37-47), in which at least one component (13a, 13b, 15, 16, 18, 19) is arranged and at which one or more gas feeds (30-36) are provided in order to introduce a gas flow into the housing (23-29), which emerges through the at least one opening (37-47). In order to effectively prevent contaminating substances from penetrating into the protection module, a light source (48-56) is arranged at the at least one opening (37-47), which light source illuminates the opening (37-47) with one or more wavelengths by which the contaminating substances can be dissociated before they penetrate through the opening (37-47).

    Abstract: Electric power is generated by using a generator (38) equipped with: a coil unit (38A) that is arranged on a barrel platform (50) and incorporates coils(39); and a magnet unit (38B) that has a magnet section (44) arranged on a protruding section (33a) of a column (30) separated from the barrel platform (50) in terms of vibration and generates an electromotive force in a non-contact state with the coils (39), and a motor (43) that drives the magnet section, and thus a wiring that supplies electric power to the barrel platform (50) does not have to be used. Accordingly, vibration that has been propagated to the barrel platform through the wiring can be precluded.

    Abstract: A reflection type illumination optical apparatus, which guides an exposure light EL to a reticle surface Ra via a curved mirror 24, a concave mirror 25, etc. includes a vacuum chamber 1 which accommodates the curved mirror 24, the concave mirror 25, etc,; and a subchamber 4D which is arranged in the vacuum chamber 1 and which accommodates the curved mirror 24. The subchamber 4D has openings 4Da, 4Db through which the exposure light EL coming into the curved mirror 24 and the exposure light EL exiting from the curved mirror 24 pass, respectively. Each of the openings 4Da, 4Db is arranged in the vicinity of a position at which the cross-sectional area of the light flux is smallest. It is possible to decrease the amount of adhesion of minute particles such as debris to the reflecting optical element, without unnecessarily enhancing the ability of the vacuum gas discharge mechanism.

    Abstract: Mittels eines Gerätes (60) zur Bestimmung von Anteilen einer Substanz in einem Gas oder Gasgemisch werden Messungen an dem Gas oder Gasgemisch zum Spülen einer Linse (10) in einem Projektionsapparat (41) für die Projektion von Strukturen auf ein Substrat (100) durchgeführt. Dabei werden die Resultate einer ersten Messung an dem der Linse (10) zugeführten Gas mit den Resultaten einer Messung des von der Linse (10) abgeführten Gases miteinander verglichen. Handelt es sich insbesondere um eine kontaminierende Substanz, die zu einer Abscheidung auf der Linse (10) unter dem Einfluß hochenergetischer Strahlung durch eine Beleuchtungsquelle (14) führt, so kann aus der Differenz auf nachteilhaft zu der Abscheidung führende photochemische Reaktionen an der Oberfläche der Linse (10) geschlossen werden. Ein Signal wird infolge des Vergleiches generiert, mit dem vorbeugende Maßnahmen gegen eine Degradation der Linse (10) getroffen werden können. Als Meßgeräte (60) können Massenspektrometer, elektrische oder optische Sensoren sowie weitere bekannte Verfahren zur Substanzanalyse eingesetzt werden.

    Abstract: The invention relates to a method for constructing an optical beam guide system in a contamination-free atmosphere and a universal optical module for said construction. The aim of the invention is to prevent contamination of the optical imaging elements during handling, assembly and adjustment. According to the invention, the imaging element is fixated aligned relative to a first reference of a support on said support outside the contamination-free atmosphere of the beam guide system, with its optical axis protected against atmospheric influences. The support, protected against atmospheric influences, is introduced into the contamination-free atmosphere of the beam guide system together with the imaging element and is fastened on the recording element, with the first reference aligned with a second reference of a recording element, thereby aligning the optical axis of the imaging element in the beam guide system. The method and the optical module according to the invention are especially suitable for applications where optical systems have to be positioned in a beam guide system ready for instantaneous use and protected from environmental influences.
