Patent DE-19839671-A1 (DE)
Inventor: SCHELTEN JAKOB
IPC: G01R33/00
Filed: 1998-09-01
Abstract: The invention relates to a sensor for measuring a magnetic field. The inventive sensor has a high level of measuring sensitivity compared to a Hall probe, comprising several electrically semiconductive layers. Said layers are arranged in the form of a power diode connected in the reverse direction, consisting of an anode layer, a cathode layer and an intrinsically conductive layer enclosed between the two. The anode layer is subdivided by insulation sections into several anode layer areas, these areas being insulated from each other. The cathode layer has an injector area on the areas opposite the insulation sections which is oppositely doped. An electron beam is formed between the injector area and the anode by applying an injection voltage to said injector area. The electron beam is distributed across the areas of the earthed anode layer areas in the form of uniform partial currents. The electron beam is diverted by a magnetic field which forms in the intrinsically conductive layer, resulting in partial currents of different strengths on the earthed anode layer areas. The magnetic field can then be evaluated by measuring these differences in strength between the partial currents.

Filed: 1998-12-08
Abstract: Ein Projektions-Mikrolithographiegerät umfaßt in seiner Beleuchtungseinrichtung in an und für sich bekannter Weise neben einer Lichtquelle und einem Objektiv eine eine besondere Bildfeldform erzeugende Einrichtung. Diese Bildfeldform genügt vorzugsweise den folgenden Bedingungen: Zum einen umfaßt sie Felder (1 bis 4), die in Richtung der Scan-Bewegung (y-Richtung) zumindest bereichsweise durch einen freien Bereich voneinander getrennt sind und die in einer eine Rotationssymmetrie zumindest grob annähernden Weise im Randbereich des zirkularen Bildfeldes (5) des nachgestellten Projektionsobjektivs liegen. Darüber hinaus muß das Integral der Menge des die der Felder (1 bis 4) durchtretenden Lichtes in Scan-Richtung über die gesamte Erstreckung der Bildfeldform in der zur Scan-Richtung senkrechten Richtung konstant sein. Eine derartige Bildfeldform (1 bis 4) ersetzt in belichtungstechnisch äquivalenter Weise eine herkömmliche rechteckige Scannerschlitzform, deren Breite in Scan-Richtung dem erwähnten Integral bei der erfindungsgemäßen Bildfeldform entspricht. Mit der erfindungsgemäßen Ausgestaltung der Bildfeldform gelingt jedoch eine annähernd rotationssymmetrische Ausleuchtung des Projektionsobjektivs, so daß nicht rotationssymmetrische, strahlungsbedingte Abbildungsfehler des Objektivs nur vermindert auftreten.
