A method and apparatus for injecting a fluid into a plasma stream with a uniform distribution and with reduced likelihood of clogging over prolonged use is provided. An injector includes a first channel portion for restricting a flow of the fluid and having a shape such that inner walls of the first channel portion are parallel to a first axis. The injector also includes a second channel portion in fluid communication with the first channel portion. The second channel portion includes a recessed portion such that inner walls of the second channel portion diverge from the first axis at a predetermined angle. The second channel portion reduces a buildup of a clogging layer on the inner walls of the second channel portion over a period of use. In addition, the injector can further include a tip portion that protrudes into the plasma. The injector can be integrated into or interchangeable within an injector system that can be designed for operation within a plasma deposition apparatus. |
