Method of coating solution on substrate surface using a slit nozzle

摘要

A slit nozzle is positioned above a surface of a substrate placed in a rotary coater, and, while the slit nozzle is translated parallel to the surface of the substrate a coating solution is ejected from the slit nozzle toward the glass substrate under conditions such that the effects of surface tension of the solution are minimized or substantially cancelled out, to uniformly coat the coating solution on substantially the entire surface of the substrate with minimum wasting of the solution.
