Abstract: A crystal growth doping apparatus and a crystal growth doping method are provided. The crystal growth doping apparatus includes a crystal growth furnace and a doping device that includes a feeding tube inserted to the furnace body along an oblique insertion direction, and a storage cover and a gate tube that are disposed in the feeding tube. The feeding tube extends from an outer surface thereof to form a placement opening, and the placement opening is recessed from an edge thereof to form an upper recessed portion and a lower recessed portion along the oblique insertion direction. The storage cover includes a storage tank and a handle. When the storage cover is disposed in the gate tube body, the gate tube body is configured to isolate an inner space of the feeding tube from the placement opening.

Abstract: A displacement mechanism includes a base, three rails, three arm assemblies, a moving platform, and three parallel linkage assemblies. The rails stand on the base. Each of the arm assemblies has a first end and a second end. The first ends are slidably connected to the rails, respectively. Each of the arm assemblies is configured to swing in a space among the rails. The moving platform is parallel to the base. Two ends of each of the parallel linkage assemblies are connected to the second end of the corresponding arm assembly and the moving platform in a multidirectional rotating way, respectively. Each of the arm assemblies substantially extends away from the base from the corresponding rail, and each of the parallel linkage assemblies substantially extends toward the base from the second end of the corresponding arm assembly.
