Abstract:
1. A method for solution coating a substrate, the method comprising: cleaning a slot die coater; sending a reverse flow of gas through a vacuum assist device after cleaning; loading the solution into the slot die coater, the slot die coater located adjacent the vacuum assist device to form a coater assembly; establishing a first distance between an edge of the slot die coater and a top surface of a priming roll; loading the substrate onto a chuck; establishing a second distance between the edge of the slot die coater and a top surface of the substrate; priming the slot die coater by sending the solution out the slot die coater onto the priming roll; positioning the slot die coater at the second distance above the substrate; coating the substrate with the solution from the slot die coater; and terminating the flow of solution to the substrate.
