Abstract
A method of cleaning a substrate, in particular, the front face of a thermal ink jet printing device, to improve subsequent thin film deposition in a single chamber plasma processing system containing fluorine-containing deposits, involves treating the substrate with a hydrogen plasma. A front face coating for a thermal ink jet device may be formed by a method involving (1) treating a substrate of the thermal ink jet device with a hydrogen plasma; (2) optionally coating the cleaned substrate with an amorphous carbon layer; and (3) coating the substrate or amorphous carbon layer with a fluoropolymer layer.
