Abstract: A gas distribution system for a polysilicon deposition reactor eliminates or mitigates the problems associated with prior art distribution systems employs at least two segments which are gas-tightly connected to one another by readily detachable fasteners, with at least one gas inlet opening and one gas outlet opening, the gas distributor of the system being mounted by readily detachable fasteners to the polysilicon reactor.

Abstract: The deposition of polycrystalline silicon onto heated filament rods in a Siemens process is improved by supplying reaction gas at least partially through nozzles in the vertical wall of the deposition reactor, at an angle of 0° to 45° to the reactor wall, towards the base plate of the reactor.
