Abstract:
1. A method for depositing a coating layer on a substrate, comprising: flowing a first fluid to an end of a first fluid-supplied roller, wherein the fluid is transferred to a portion of the outer surface of the first roller; flowing a second fluid to an end of a second fluid-supplied roller, wherein the fluid is transferred to a portion of the outer surface of the second roller, contacting at least one of the first and second rollers to the substrate surface; and rotating the first and second rollers to produce the coating layer on the substrate surface, wherein the coating layer comprises a mixture of a first liquid coating formed by the first roller and a second liquid coating formed by the second roller, and wherein the coating layer is non-uniform in thickness in the direction along the length of the first or second roller, wherein the thickness non-uniformity is configured to compensate for a non-uniform subsequent process so that after the non-uniform subsequent process, a uniform coated substrate is achieved from the combination of the non-uniform coating and the non-uniform subsequent process.
