Abstract: A sustainable manufacturing method for polycrystalline silicon using a fluidized bed reactor is provided to maximize the productivity of a fluidized bed reactor without damaging the mechanical stability of a reactor by periodically and easily removing the silicon deposit on the inner wall of a reaction pipe during a process for transferring the silicon deposit without disassembling the reactor. Reaction gas is supplied by a reaction gas injecting unit to deposit silicon on the surface of silicon particles in contact with the reaction gas while silicon deposit are accumulated on the inner wall of a reaction pipe surrounding a reaction region. After the supply of the reaction gas is stopped, part of the silicon particles is exhausted to the outside of the fluidized bed reactor to prevent the silicon particles remaining in the reaction pipe from exceeding the height of a reaction gas outlet of the reaction gas injecting unit. Etch gas capable of reacting with the silicon deposit to generate a silicon compound of a gas phase is supplied to a space of the reaction region to eliminate the silicon deposit. After the supply of the etch gas is stopped, silicon particles are supplemented to the inside of the reaction pipe to form a layer of silicon particles in the reaction region. The silicon particles are fabricated by repeating a silicon deposit transferring cycle including the abovementioned processes.
