Coating, particularly a method for uniformly depositing a micro thin layer of fluid upon the surface of an object such as a substrate, or the like. Flowing the coating material through a permeable and sloping surface, so as to develop a downward laminar flow of coating material on the outside of the sloping surface. The object to be coated is advanced tangentially to the flow of coating material such that the surface to be coated intersects laminar flow of coating material at the apex of the sloping surface. Meniscii of coating material are supported both at the leading edge and the trailing edge of coating material in contact with the surface to be coated. The uniform disengagement and drainage of deposited excess coating material from the coated surface are ensured by uniform meniscii and the constant downward laminar flow of coating material on the outside of the sloping surface.

Method of meniscus coating of an object comprising: A. Flowing a coating material from the interior and through the wall of a stationary, permeable cylindrical surface, so as to develop downward laminar flow of coating material on the outside of the cylindrical surface; B. Advancing an object to be coated in a plane tangentially to said laminar flow of coating material, such that a leading surface portion of the object intersects laminar flow of coating material at the apex of the cylindrical surface; C. Supporting uniform meniscii of flowing coating material both at the leading edge and the trailing edge of coating material contacting said object; and D. Uniformly disengaging the coated surface of the object from said lamainar flow of coating material. Method of meniscus coating of an object as in claim 1, further including initially scrubbing and rinsing said object prior to said flowing of coating material. Method of meniscus coating of an object as in claim 9, further including plasma cleaning of the object surface prior to said flowing of coating material.
