摘要： A novel capillary die and crystal growing method are provided for growing a hollow cristalline body by EFG. Inner and outer annular moats (114, 116) surround the die tip. Passageways (180) are provided for supplying melt (29) to those moats from a crucible (24), so that melt (29) in said moats will wet and cover the inner and outer exterior surfaces of the die tip during growth of a hollow crystalline body. The novel die may be constructed so as to have a lower die tip and a shorter capillary than EFG dies heretofore used to successfully grow hollow bodies. The die design facilitates keeping the temperature of the die tip substantially uniform about its circumference, thereby improving uniformity of thickness of the wall of the crystalline body (112) grown from a film of melt (110) on the die tip. The moats reduce the likelihood of the growth process being interrupted or adversely affected by flooding of the die. In the event the growth meniscus breaks, liquid silicon is captured in the moats, thereby preventing or reducing the likelihood of flooding of the die.

摘要： A control system for controlling the operation of a system (18) for replenishing the melt in the crucible (24) of an apparatus (20) for growing tubular crystalline bodies (22) of a selected material. The melt replenishment system (18) comprises a container (302) for storing solid particles of said selected material and a dispenser (306) for transporting the particles from the container (302) to the crucible (24). The control system controls the rate at which the dispenser (306) transports particles from the container (302) to the crucible (24) based on the weight of the solid particles stored in the container (302), the weight of the crystalline body (22), and the pressure inside the crystalline body (22). Additionally, the control system may be adapted to control the temperature of the crucible heater (26) of the apparatus (20). Compensation is provided by this invention for weight measurement errors that are created by pressure fluctuations within the tubular crystalline body (22).

摘要： A control system for controlling the operation of an apparatus for growing tubular crystalline bodies. The control system comprises a weight sensor (100) for measuring the weight of the crystal, a pressure sensor (102) for measuring the pressure inside the crystal, and a controller (105) coupled to the weight, length and pressure sensors for controlling the operation of the crystal growing apparatus. The controller is coupled to the die heater (26) of the apparatus for controlling the temperature of melt contained in the crucible (24) of the apparatus based on the outputs of the weight, length and pressure sensors. To ensure the wall of the tubular crystalline body is maintained at a substantially uniform thickness, precise measurement of the weight of the body must be made. Compensation is provided by this invention for weight measurement errors that are created by pressure fluctuations within the tubular crystalline body.
