Abstract: An electrode anchoring structure in a crystal-growing furnace includes at least one graphite electrode pillar, at least one metal electrode pillar, at least one anchoring base, and at least one locking nut, wherein the graphite electrode pillar is engaged with a nut base of the metal electrode pillar, and the at least one metal electrode pillar is, through the anchoring base, is secured to furnace wall. Therefore, the at least one graphite electrode pillar acts both as weight support and electrical-conducting electrode. Since the flange welded on furnace wall has a greater area exposed to the atmosphere, a desirable cooling effect can be achieved, and temperature drop can be expedited if water spray is performed. The anchoring base is provided with a resilient washer, such that a resilient force can be employed to adjust loading of each graphite electrode pillar in an axial direction.

Abstract: A crystal-growing furnace system with an emergent pressure-release arrangement includes an isolated chamber and a furnace upper body. The top board is provided with an opening and three first guides, and the furnace upper body with a lower opening and three second guides, wherein the lower opening of the furnace upper body covers, correspondingly, on the opening of the top board. In case a crystal-growing furnace, combined oppositely by the furnace upper body and the furnace lower body, has an over-high internal pressure, the pressure will overcome the weight of, and lift up the furnace upper body. At this moment, the furnace upper body will slightly move upward and away from enclosing the furnace lower body, so that the over-high internal pressure in the furnace will be released immediately to prevent the furnace from being exploded and from resulting in public accidents.

Abstract: A crystal-growing furnace having a slurry drainage duct structure includes a furnace body, a supporting table, a loading frame, a plurality of eaves elements, and a set of eaves gutters. The supporting table includes a table plate and a plurality of supporting posts. The loading frame includes a lower plate and four side plates, where four elongated eaves boards descend from sides of the lower plate. Four eaves gutters, having V-shaped grooves, are connected with one another and disposed beneath the four eaves elements correspondingly. Any high-temperature silicon slurry leaks from a furnace crucible will be guided by the elongated eaves boards into the V-shaped grooves of the eaves gutters to prevent the silicon slurry from flowing along the periphery of the table plate and down to the supporting posts.

Abstract: A supporting table having heaters inside a crystal-growing furnace includes a table plate and a plurality of supporting posts, wherein the supporting posts support the table plate and are, respectively, electrically connected with the heaters. Each supporting post includes, among others, a graphite electrode post, a metal electrode post, and an anchoring base. The supporting posts are each with its graphite electrode post screwed to a nut portion of the metal electrode post, and with the metal electrode post fixed to a wall of the crystal-growing furnace. The anchoring base includes, among others, a flange and an elastic washer, where the flange is welded to the wall of the furnace, and with the help of elasticity adjustment of the elastic washer, the supporting table can bear an equal distribution of loading from the supporting posts.

Abstract: A cooling structure for the body of a crystal-growing furnace includes an upper body and a lower body. The upper body includes an outer upper shell and an inner upper shell, wherein an upper enclosing space is formed between the outer upper shell and the inner upper shell. The lower body includes an outer lower shell and an inner lower shell, wherein a lower enclosing space is formed between the outer lower shell and the inner lower shell. A plurality of water pipes are arranged, respectively, around the upper and the lower enclosing spaces, wherein plural spraying holes are provided on each of the water pipes. With the help of a pump, water from an outside water source is drawn through the spraying holes of the water pipes so as to cool down the body of the crystal-growing furnace. In adding an exhaust fan, warm air in the upper enclosing spaces can be driven out speedily.

Abstract: A crystal-growing furnace system includes an isolated chamber, a furnace upper body, and a controller room, wherein the isolated chamber and the controller room are arrayed and isolated from each other. A door is provided between the controller room and the isolated chamber so as to isolate or communicate the controller room from or with the isolated chamber. The isolated chamber includes, among others, a top board, a furnace lower body, and a lifting device, wherein the lifting device moves the furnace lower body upward and closes the furnace upper body so as to form an enclosed crystal-growing furnace, or downward and departs from the furnace upper body. Because the isolated chamber and the controller room are arranged isolating from each other, noise, high temperature, and dust pollution can be isolated from the isolated room, so that personnel working in the controller room can be assured of safety and health.

Abstract: A crystal-growing furnace with a heating improvement structure includes a furnace body, a supporting table, a top heater, and a bottom heater. When the silicon material around the top heater is melted, molten silicon slurry will flow directly into the spacing among particles of the silicon material. This will expedite internal part of the silicon material to absorb energy. As a result, a desirable cycle will be established to expedite melting the whole silicon material in the crucible. The crucible is heated at the bottom thereof by the bottom heater directly so as to enhance efficiency in melting the silicon material in the crucible, and to save energy and time consumed by the crystal-growing furnace. Further, since both of the top and the bottom heaters are symmetrical with one another, the crucible can be heated uniformly. This not only saves energy and makes the heating job convenient, but also saves cost in manufacture.
