摘要： This invention relates to a method of manufacturing an ink jet printhead, said printhead comprising a substrate (10) and an ink barrier layer (20) formed on said substrate (10), said method comprising the steps of: arranging a nozzle plate (30) in which there is formed a plurality of nozzles (82) suitable for the ejection of ink drops, said nozzle plate (30) comprising an upper surface (31) and a lower surface (32), said upper surface being on the side of the ejection of ink drops and said lower surface being opposite to said upper surface; depositing on said upper surface (31) a first coating (40) including a first layer (41) comprising silicon carbide, while maintaining said nozzle plate (30) at a first deposition temperature not larger than 250°C; depositing on said lower surface (32) a second coating (60) including a second layer (61) comprising silicon carbide, while maintaining said nozzle plate (30) at a second deposition temperature not larger than 250°C; positioning said nozzle plate (30) onto said ink barrier layer (20) by bringing into contact said second coating layer (61) with said ink barrier layer (20). The first layer (41) is deposited before said second layer (61).
