Abstract: A pellicle which can prevent the formation of foreign-matter deposits on a photo-mask during laser beam irradiation or storage and keep a high pattern accuracy for an extended period of time even when an exposure is made using a KrF or ArF excimer laser beam by removing deposit-causing materials from the pellicle itself in advance. During a pellicle producing process, a component member used or a completed product is heated or placed under pressure to thereby remove in advance substances produced from the component member used or the completed product.

Abstract: A desired isomer is selectively prepared by phosphorolyzing and isomerizing an anomer mixture of a 1-phosphorylated saccharide derivative while crystallizing one of the isomers to displace the equilibrium. Furthermore, using the action of a nucleoside phosphorylase, a nucleoside is prepared from the 1-phosphorylated saccharide derivative obtained and a base with improved stereoselectivity and a higher yield. This process is an anomer-selective process for preparing a 1-phosphorylated saccharide derivative and a nucleoside.
