Abstract:
A lift arm can be rotatably mounted to a crystal growing apparatus to service a hot-zone of the crystal growing apparatus. A low-speed, high-power lift arm actuator can control vertical positioning of the lift arm. Movable clamp arms secured to the lift arm can engage a lip of a furnace tank to facilitate lifting and moving the furnace tank to a desired location by correlated raising, lowering, or rotating of the lift arm. A winch mounted to a distal end of the lift arm can control spooling of a cable that passes through an interior of the lift arm and out an opening between the clamp arms. The cable can include an attachment mechanism for coupling to a crucible. The winch can thus lift the crucible at vertical speeds far in excess of the lift arm actuator's vertical speed.
A vacuum system for silicon crystal growth includes a silicon crystal growth chamber, a first vacuum pipe, a second vacuum pipe, and an oxides container. The first vacuum pipe is coupled to the chamber and has within a first brush that is movable in a first direction for removing internal oxides. The second vacuum pipe is coupled to the first vacuum pipe for receiving the internal oxides via the first brush and has within a second brush that is movable in a second direction different from the first direction. The second brush transports the received internal oxides away from the first vacuum pipe. The oxides container is coupled to the second vacuum pipe for receiving the internal oxides via the second brush.
