METHOD AND APPARATUS FOR APPLYING THIN FLUID COATING STRIPES

摘要

A system for coating a substrate with ultra-thin layers in stripes includes moving the substrate (32) through a coating station and forming a composite layer (48) including coating fluids (244, 248) and a carrier fluid (252). The composite layer (48) 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 to interpose the coating layers 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.
