Background technology
21 century, world energy sources crisis facilitates the development of photovoltaic market, and crystal silicon solar energy battery is the leading products of photovoltaic industry.Along with countries in the world are to the further attention of solar photovoltaic industry, particularly developed country has formulated a series of support policy, encourage to develop solar energy, in addition, along with the continuous expansion of silicon solar cell application surface, the demand of solar cell is increasing, and the demand of silicon single crystal material is also just increasing.
Monocrystalline silicon is a kind of semi-conducting material, and be generally used for and manufacture integrated circuit and other electronic components, monocrystalline silicon growing technology has two kinds: one is zone-melting process, and another kind is vertical pulling method, and wherein vertical pulling method makes the current method generally adopted.
The method of monocrystalline growth with czochralski silicon is as follows: the silica crucible highly purified polycrystalline silicon raw material being put into single crystal growing furnace, then heat fused under the protection of slumpability gas is had in low vacuum, the monocrystalline silicon in particular growth direction (being also called seed crystal) is had to load in seed crystal clamping device one, and seed crystal is contacted with silicon solution, the temperature of adjustment molten silicon solution, make it close to melting temperature, then seed crystal is driven to stretch in the silicon solution of melting and to rotate from top to bottom, then slowly upper lifting seed is brilliant, now, monocrystalline silicon enters the growth of conical section, when the diameter of cone is close to aimed dia, improve the hoisting velocity of seed crystal, monocrystalline silicon body diameter is made no longer to increase and enter the middle part growth phase of crystal, at the end of monocrystalline silicon body growth is close, improve the hoisting velocity of seed crystal again, monocrystalline silicon body departs from molten silicon gradually, form lower cone and terminate growth.The monocrystalline silicon grown out in this way, its shape is two sections of tapered cylinders, is cut into slices by this cylinder, namely obtains single-crystal semiconductor raw material, and this circular single crystal silicon chip just can as the material of integrated circuit or solar energy.
In photovoltaic industry, the general cross section of silicon single crystal rod adopting vertical pulling method to make is original shape, but need under many circumstances the silicon rod of circle to be cut into square so that use, at present, for how, circular silicon rod being cut into square silicon rod is mostly adopt diamond saw blade to cut, because the thickness of diamond saw blade is generally about 3mm, if with the diamond saw blade cutting silicon single crystal rod that 3mm is thick, just have the kerf loss of 3mm, cut four faces and at least will waste the thick monocrystal material of 12mm, the utilization rate of monocrystalline is lower, and monocrystalline is expensive, the low production cost of monocrystalline silicon that will cause of Single Crystal Utilization Ratio increases greatly, and, use diamond saw blade to cut height and cut seed crystal, the cut surface of seed crystal is rough, also need to carry out subsequent handling process to cut surface, not only complex procedures and cost are also comparatively, in addition, existing cutter sweep complex structure, cutting is got up very inconvenient.
