Abstract

PURPOSE:To shield far ultraviolet rays with a long-life mask having high hardness and a thin film low is reflectivity, by using as a film for shielding far ultraviolet rays an alumina film containing >=1 kinds of metal, semimetal elements, or oxides of these elements, or an organic compound. CONSTITUTION:An alumina film 2 containing >=1 kinds selected from metal and semimetal elements, oxide and the like compound of these elements, and organic compounds are formed on a substrate 1 made of transparent synthetic quartz glass. On this film 2 a resist film pattern 3 is formed, and the film 2 is etched by reactive sputtering using the pattern 3 as a mask to form the pattern of the alumina film 2. The obtained mask has the substrate 1 and the pattern 2 both high in hardness, and the film 2 low in reflectivity, so the substrate 1 is insusceptible to scratching in repeated uses when using this resist pattern on a silicon substrate in the contact exposure system, and it can be used for a long term as a mask for shielding far ultraviolet rays.
