Abstract

PURPOSE:To enable the safe and stable etching at an appropriate etching speed as well as to reduce a cost by constituting the titled etching liquid from a specific composition of ammonium hydroxide, hydrogen peroxide and water. CONSTITUTION:The etching liquid for the phosphorus containing glass is characterized in constituted from 7-45wt% of ammonium hydroxide, 7-20wt%. of hydrogen peroxide and a balance of water. This etching liquid has an appropriate etching speed and it is not necessary to add an expensive chemical agent for controlling the etching speed as a conventional etching liquid as well as handling is safe and accidents are not generated during etching work.
