Abstract:
1. A deposition system for coating a substrate, comprising: a heating mechanism to heat the substrate; one or more coating rollers, each coating roller comprising a porous layer for accepting and retaining a liquid to transfer to the substrate by rollingly contact; a temperature controlling device coupled to the liquid to control the liquid temperature to be below room temperature, a liquid reservoir to provide the liquid to the one or more coating rollers, wherein the one or more coating rollers contact the liquid in the liquid reservoir for accepting the liquid, wherein the temperature controlling device is coupled to the liquid within the liquid reservoir, a physical barrier surrounding the one or more coating rollers, the physical barrier comprising restrictive fluid communication between two portions of the liquid in the liquid reservoir isolated by the physical barrier, a temperature controlling device coupled to the physical barrier to establish a temperature gradient between the two portions of the liquid in the liquid reservoir.
