Abstract

A new approach to the application of precision coating to flat panel is presented. This coating method is based on the meniscus coating principal, which provides a very uniform and repeatable coating film to the inverted side of the flat panel of virtually any size. Film thickness of typical 400 angstroms to seven microns can be applied with a film variation of +/- 2%. The main advantages using this coating technique are : (1) no coating liquid edge build-up, (2) insensitive to dust contamination, (3) insensitive to machining accuracy and substrate surface topography, and (4) extremely high transfer efficiency.
