Description
изобретение относитс к составам стекол, используемым при изготовлении полупроводниковых приборов дл фотошаблонов или хромовых масок.The invention relates to glass compositions used in the manufacture of semiconductor devices for photo masks or chrome masks.
Известно стекло, включающее SiO2, СаО, ZnO, NaaO, , ВаО и К2О. . Цель изобретени -снизить спектральное поглощение в ультрафиолетовой области спектра.Known glass, including SiO2, CaO, ZnO, NaaO, BaO and K2O. . The purpose of the invention is to reduce the spectral absorption in the ultraviolet region of the spectrum.
Достигаетс это тем, что стекло содержитThis is achieved by the fact that the glass contains
