Patent ID: 8580353

Claim:
A method for producing a glass substrate coated with a conductive film, comprising the steps of: A. placing the glass substrate into a vacuum treatment chamber; B. introducing a gas into the vacuum treatment chamber provided with an electron gun; C. providing electric power having a voltage level ranged between 800˜1200V to the electron gun, so that the electron gun emits an electron beam and the electron beam strikes the gas to generate an ion source; D. subjecting a surface of the glass substrate to a pretreatment by directing the ion source towards the surface of the glass substrate; and E. coating a conductive film onto the pretreated surface of the glass substrate after the pretreatment, so that the pretreated surface of the glass substrate is coated with the conductive film having a reduced surface electrical resistance and a higher crystalline level as compared to a conductive film coated on a glass substrate that has not been subjected to the pretreatment in Step D.
