Abstract:
An etch method comprising:providing a material layer consisting essentially of a group member selected from the group consisting of an indium oxide (InO), a tin oxide (SnO), a mixture of indium and tin oxides, a compound of indium and of tin and of oxygen having the general formulation In.sub.x Sn.sub.y O.sub.z where z is substantially greater than zero but less than 100% and where the sum x+y fills the remainder of the 100%, and a mixture of the preceding ones of said group members;supplying a reactive gas including a halogen-containing compound and an oxygen-containing compound to a vicinity of the material layer; andsupplying an electric field to react the supplied reactive gas with the material layer so as to form volatile byproducts of reactive gas and the material layer.
