Abstract: A system of gas lines for a processing chamber and a method of forming a gas line system for a processing chamber are provided. The system of gas lines includes electropolished multi-way valves that connect electropolished linear gas lines. By using multi-way valves rather than tee-fittings and electropolishing the linear gas lines, the nucleation of contaminating particles in the system of gas lines may be reduced.
