Method and apparatus for applying thin fluid coatings

摘要

A system for coating a substrate with an ultra-thin layer includes moving the substrate through a coating station and forming a composite layer including a coming fluid and a carrier fluid. The composite layer flows at a rate that is sufficiently high to form a continuous flowing fluid bridge of composite layer to the substrate surface and to contact the substrate with the flowing composite layer to interpose the coating layer between the substrate and the carrier fluid. The carrier fluid is removed while leaving the coating fluid deposited on the substrate as a coating layer.
