Abstract: Tin oxide (SnO2) is etched by forming a layer of a metal such as aluminum on the portions of the SnO2 surface to be etched, and then contacting the metal with an aqueous solution of hydrochloric acid. Passage of a current through the tin oxidemetal composite as cathode while in contact with the solution as electrolyte may be employed to speed up removal of SnO2.
Abstract translation: 通过在要蚀刻的SnO 2表面的部分上形成诸如铝的金属层,然后使金属与盐酸水溶液接触来蚀刻氧化锡(SnO 2)。 通过氧化锡 - 金属复合物作为阴极同时与作为电解质的溶液接触的电流可以用于加速除去SnO 2。
