摘要： A modular furnace is fabricated from at least one module having a frame, a removable cover mounted to the frame, exterior cover panels on the frame, and an insulated case fastened to the interior of the module. A conveyor assembly extends through the module. A plurality of process zones, such as heating and cooling zones, are disposed within the module. Field replaceable universal blower assemblies are associated with each process zone. The motor shaft in each blower assembly is provided with a sealed bearing in the motor housing. Insulation within each module is held in place by gas permeable fabric covering large vent openings in cover panels to allow oxygen to diffuse out of the insulation rapidly upon start up.

摘要： A novel capillary die and crystal growing method are provided for growing a hollow crystalline body by EFG. Inner and outer annular moats surround the die tip. Passageways are provided for supplying melt to those moats from a crucible, so that melt 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 the uniformity of thickness of the wall of the crystalline body grown from a film of melt 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 and associated growth apparatus.

摘要： A forced convection furnace gas plenum having a mixing chamber to provide a heated gas of a more uniform temperature is presented. The plenum includes a heating element for heating gas and an orifice plate for metering the flow of heated gas to product within the furnace. A heater plate having larger apertures than those of the orifice plate is disposed between the heating element and the orifice plate. The apertures in the heater plate are sized to allow heated gas to pass therethrough into the mixing chamber, located between the heater plate and the orifice plate, with minimal pressure loss. The heated gas mixes in the mixing chamber, causing the temperature to become more uniform before the gas exits through the orifice plate to impinge on the product.

The movable guide face has a first position and a second position, whereby a narrower IC boat is receivable in the first position and a wider IC boat is receivable in the second position. In a further embodiment, the boat carrier comprises a base member, a fixed guide assembly having a fixed guide face, and an opposed guide assembly having an inner and outer guide face, whereby a boat having a first or second width is receivable. In yet another embodiment, the boat carrier comprises a further fixed guide assembly and a further opposed guide assembly, thereby forming dual sets of guides, wherein each set of guides is capable of receiving a boat having a first or second width.

摘要： Embodiments related to sheet production are disclosed. A melt of a material is cooled to form a sheet of the material on the melt. The sheet is formed in a first region at a first sheet height. The sheet is translated to a second region such that it has a second sheet height higher than the first sheet height. The sheet is then separated from the melt. A seed wafer may be used to form the sheet.
