SURFACE TREATING FLUID FOR FINE PROCESSING OF MULTI-COMPONENT GLASS SUBSTRATE

摘要

A surface treatment solution for finely processing a glass substrate containing multiple ingredients like the one used for the construction of a liquid crystal-based or organic electroluminescence-based flat panel display device, without evoking crystal precipitation and surface roughness. An etching solution of the invention contains, in addition to hydrofluoric acid (HF), at least one acid whose dissociation constant is larger than that of HF. The concentration of the acid in the solution is adjusted.
