METHOD OF SELECTIVELY ETCHING PATTERN WITHIN A GLASS

摘要

PURPOSE: A method for selectively etching a pattern inside a glass is provided to reduce a process cost by selectively forming a pattern inside a glass through a mask and an etching solution. CONSTITUTION: A barrier and a glass are bonded through a bonding agent(S10). A mask is formed on the glass with a predetermined pattern(S20). A part in which the mask is not formed in the glass is selectively etched by injecting an etching solution inside a space formed by the barrier(S30). The barrier is made of an acid-resistant material which is not rusted by the etching solution. The acid-resistant material is one of Teflon, polypropylene, and glass.
