Abstract: PURPOSE:To form a uniform pattern in the entire area of a glass substrate by comparing the pattern width of an innermost area in a pattern area on the glass substrate with that of an outermost area and dripping a liquid developer from a nozzle in the intermediate pattern area when the pattern width of the outermost area is smaller. CONSTITUTION:When the liquid developer 3 is dripped from only the nozzle inside the pattern area while the glass substrate 2 which is exposed the pattern is rotated spirally, the liquid developer 3 flows on the glass substrate 2 from inside to outside to perform development processing. While the development is advanced, laser beam is projected perpendicularly on two points in the innermost area and outermost area of the pattern area simultaneously at all the times and an arithmetic unit 10 calculates the pattern width. Then when the pattern width (x) of the innermost pattern area is larger than the pattern width (y) of the outermost area, a comparator 12 sends an indication to a solenoid valve 11 so as to drip the liquid developer from the nozzle in the intermediate pattern area, but when smaller, an instruction is sent to the solenoid valve 11 so as to drip pure water from the nozzle in the intermediate pattern area. Consequently, the uniform pattern is formed over the entire surface of the substrate.
