Substrates 5 to be coated are placed in the chamber 1 and remain stationary throughout the coating operation. The coating media is transferred from the reservoir 2 to the chamber 1 via a filter 7 by pressured nitrogen 4. When the substrates are covered, the solution is allowed to drain by gravity by opening valve 3, the rate being controlled by the orifice in the valve 6. The coating is accomplished without moving the substrates. After deposition is complete, the substrates can be removed for further processing.
