Abstract: Methods for cleaning a stannane distributions system. A stannane distribution system connecting a stannane supply source and a semiconductor manufacturing tool is provided. Stannane is flown through the system, and a tin layer is formed on the components of the distribution system. This tin layer is then cleaned from the distribution system without the use of liquid cleaning chemicals.
