Plasma deposition apparatus and method for making polycrystalline silicon

A plasma deposition apparatus for making polycrystalline silicon including a chamber for depositing said polycrystalline silicon, the chamber having an exhaust system for recovering un-deposited gases; a support located within the deposition chamber for holding a target substrate having a deposition surface, the deposition surface defining a deposition zone; at least one induction coupled plasma torch located within the deposition chamber and spaced apart from the support, the at least one induction coupled plasma torch producing a plasma flame that is substantially perpendicular to the deposition surface, the plasma flame defining a reaction zone for reacting at least one precursor gas source to produce the polycrystalline silicon for depositing a layer of the polycrystalline silicon the deposition surface.
