Patent ID: 7679086

Claim:
A method for manufacturing an electro-optic device, comprising: an electroconductive film forming step that forms an electroconductive film over at least a first and second surfaces of a substrate, the first and second surfaces being on opposite sides of the substrate from each other; a first electroconductive film removing step that removes the electroconductive film from the first surface of the substrate; a thin layer forming step that forms layers on the first surface of the substrate; and a second electroconductive film removing step that, after the thin layer forming step, removes the electroconductive film from the second surface, at least one of the first electroconductive film removing step and the second electroconductive film removing step being performed by applying a chemical agent capable of etching the electroconductive film onto one of the first and second surfaces while the substrate is rotated, while jetting a dry gas onto the other of the first and second surfaces.
