Abstract
A method for coating flat substrates with a liquid, the method comprising: pressurizing liquid within a coat head wherein the liquid has a viscosity of at least thirty centipoises; forming a meniscus of liquid at an orifice in the coat head; contacting the meniscus of the liquid to the substrate; and moving the meniscus relative to the substrate. A system for coating a flat substrate with liquid, the system comprising: a coat head filled with liquid by capillary action, wherein the viscosity of the liquid is at least thirty centipoises; a pressurizer of the liquid that forms a meniscus at an orifice in the coat head; a contacter of the meniscus to the substrate; and a mover of the meniscus relative to the substrate. A system for coating a flat substrate with liquid, the system comprising: a coat head filled with liquid, wherein the viscosity of the liquid is at least thirty centipoises; a pressurizer of the liquid that forms a meniscus at an orifice of the coat head; a contacter of the meniscus to the substrate; a mover of the meniscus relative to the substrate; a regulator of liquid pressure at the base of the coat head; and a replenisher of liquid that replenishes liquid taken from the coat head with liquid in a reservoir.
