发明名称 Method and apparatus of growing silicon single crystal and silicon wafer fabricated thereby
摘要 Disclosed is a method of fabrication of high quality silicon single crystal at high growth rate. The method grows silicon single crystal from silicon melt by Czochralski method, wherein the silicon single crystal is grown according to conditions that the silicon melt has an axial temperature gradient determined according to an equation, {(DeltaTmax-DeltaTmin)/DeltaTmin}x100<=10, wherein DeltaTmax is a maximum axial temperature gradient of the silicon melt and DeltaTmin is a minimum axial temperature gradient of the silicon melt, when the axial temperature gradient is measured along an axis parallel to a radial direction of the silicon single crystal.
