Patent ID: 8895425

Claim:
A method of forming a channel layer of an electric device, comprising: (a) providing a conductive substrate having an insulating layer formed on a surface of the substrate; (b) immersing the conductive substrate and a metal to be plated into an electrolyte solution; and (c) applying a voltage to generate a tunneling current caused by electrons passing through the insulating layer from the conductive substrate using the conductive substrate and the metal as respective electrodes, and bonding ions of the metal within the electrolyte solution with the electrons that have tunneled through the insulating layer to form a metal channel layer on the insulating layer, after (a) providing a conductive substrate with an insulating layer, forming at least one electrode layer on the insulating layer; wherein in (c) bonding the ions of the metal with the electrons, when the metal channel layer is connected to the at least one electrode layer, bonding the ions of the metal with the electrons is stopped at the metal channel layer.
