Abstract:
1. A silicon reactor system, comprising: a reaction chamber including at least a base plate fixed within the reaction chamber and an enclosure operably connected to the base plate; at least one silicon filament attached to the base plate; an electrical current source connected to ends of the at least one filament for supplying a current to the at least one filament; a gas source operably connected to the reaction chamber to allow a silicon-containing gas to flow through the reaction chamber; and a standpipe comprising a pipe body having (i) an inlet end operably connected to the gas source and (ii) an outlet end exposed within the reaction chamber for directly injecting the gas flow into the reaction chamber, said outlet end being a termination of said pipe body that does not add structure to said pipe body, said outlet end being located at a height above the ends of the at least one filament that are connected to the electrical current source, said standpipe comprising silicon and being configured to receive deposits of polysilicon in the reaction chamber.
