摘要:
An etchant composition that allows simplification and optimization of semiconductor manufacturing process is presented, along with a method of patterning a conductive layer using the etchant and a method of manufacturing a flat panel display using the etchant. The etchant includes nitric acid, phosphoric acid, acetic acid, and an acetate compound in addition to water.
