Abstract: The present disclosure in an exemplary embodiment relates to an apparatus for manufacturing polysilicon. The apparatus for manufacturing polysilicon comprises a base plate; a container body coupled to the base plate; at least one rod; a reaction gas source and a power supply. The at least one rod is configured to have legs respectively connected with three electrodes installed on the base plate and to be disposed in the container body. The reaction gas source is configured to communicate with the container body for supplying a reaction gas into the container body. The power supply is configured to connect with the electrodes for supplying an electric current to energize the rod to generate heat.
