Abstract:
1. A metal-oxide-semiconductor (MOS) comprising a substrate, at least one dielectric, and at least one metal electroplated directly onto said at least one dielectric according to a method comprising: (i) providing said at least one dielectric on a conducting and/or semiconducting substrate wherein said at least one dielectric is at least partially immersed in an electrolyte solution or melt, said electrolyte solution or melt comprising at least one active ingredient for an electrochemical process: (ii) providing at least one auxiliary electrode at least partially immersed in the electrolyte solution or melt and at least one reference electrode at least partially immersed in the electrolyte solution or melt: (iii) applying a voltage between the substrate and the reference electrode and passing a current through the dielectric to said auxiliary electrode enabling an electrochemical process at the dielectric: (iv) electroplating or electrodeposition of a conducting or semiconducting material on the dielectric: (v) electrochemical modification of the dielectric: (vi) electrochemical etching: (vii) electropolishing: and (viii) electrodeposition of an insulator or oxide from the electrolyte.
