摘要： A method of fabricating parts of silicon, preferably virgin polysilicon formed by chemical vapor deposition of silane, and assembling them into a complex structure, such as a silicon tower or boat for removably supporting a plurality of silicon wafers during thermal processing. The virgin polysilicon is annealed to above 1025° C. before it is machined into a predetermined shape. After machining, the silicon parts are annealed in an oxygen ambient. The machined parts are then assembled and joined together followed by another anneal of the assembled structure. A preferred embodiment of the tower includes four legs secured on their ends to two bases. A plurality of slots are cut in the legs allowing slidable insertion of the wafers and support for them. The bases may be either virgin poly or monocrystalline silicon and be either integral or composed of multiple parts.

摘要： A method of fabricating the parts and assembling them into a complex structure, such as a silicon tower or boat for removably supporting a plurality of silicon wafers during thermal processing. A preferred embodiment of the tower includes four legs secured on their ends to two bases. A plurality of slots are cut in the legs allowing slidable insertion of the wafers and support for them. The legs preferably have a rounded wedge shape with a curved front surface of small radius cut with the slots and a back surface that is either flat or curved with a substantially larger radius. Preferably, the legs are machined from virgin polysilicon formed by chemical vapor deposition from silane. The bases may be either virgin poly or monocrystalline silicon and be either integral or composed of multiple parts. Virgin polysilicon is preferably annealed to above 1025° C. before machining. Silicon parts may be joined by applying a spin-on glass between the parts and annealing the assembly. After assembly, the surface of a tower is subjected to sub-surface working.

摘要： A method and apparatus for welding together two silicon workpieces (20, 22) without the formation of cracks along the weld. In a first embodiment, current (34, 36) is passed through one or both of the workpieces to heat them to between 600 and 900° C. Then an electric, laser, or plasma welder (38, 40) passes along the seam (24) between the workpieces to weld them together. In a second embodiment, current (34) is passed through a plate (60), preferably formed of silicon, which either supports the workpieces or is brought into contact with at least one of them, whereby the workpieces are preheated prior to the welding operation.

摘要： Two silicon workpieces (20, 22) welded together into one member without the formation of cracks along the weld. It may be formed by a first method in which current (34, 36) is passed through one or both of the workpieces to heat them to between 600 and 900° C. Then an electric, laser, or plasma welder (38, 40) passes along the seam (24) between the workpieces to weld them together. In a second forming method, current (34) is passed through a plate (60), preferably formed of silicon, which either supports the workpieces or is brought into contact with at least one of them, whereby the workpieces are preheated prior to the welding operation.
