Abstract

Equipment for producing a single crystal in each of a plurality containers by thermally treating raw material in each container, the equipement including heaters corresponding to each of the containers, an elevator to move each of the containers up or down relative to each respective heater, and a connecting member to connect at least one of the container and the heater, each of a plurality of sets of the containers and the heaters, mechanically to the elevator, wherein each container is moved vertically relative to the respective one of the heaters by driving the elevator. The container is passed through an area of thermal treatment formed by the heater so that a melt is continuously formed in the raw material inside the container. The single crystal is continuously produced in the container by solidifying the melt.
