Vorrichtung zum Belichten eines Substrats, Photomaske und modifiziertes Beleuchtungssystem der Vorrichtung und Verfahren zum Bilden eines Musters an einem Substrat unter Verwendung der Vorrichtung

摘要

The mask has polarization patterns (210) arranged on a transparent substrate (200), which includes lines extending parallel to each other and the lines are opaque to light. The lattice patterns occupying spaces between the lines, have a series of stripes opaque to light and extending perpendicular to the lines of line/space pattern. The stripes have a pitch smaller than wavelength of light. Independent claims are also included for the following: (1) composite polarization modified illuminating system; (2) exposure apparatus; and (3) method of forming line/space circuit pattern.
