Method for preparing monocrystalline silicon by using czochralski method

The application belongs to the technical field of production of monocrystalline silicon and particularly relates to a method for preparing the monocrystalline silicon by using a czochralski method. The method comprises the following steps: after a silicon material is melt in a single crystal furnace, heating power of the single crystal furnace decreases rapidly; after a temperature controller controls the temperature in the single crystal furnace to be stabilized, a seed crystal makes contact with the liquid level and then necking is carried out; after necking reaches a certain height, dislocation-free shouldering is performed and a crystal grows; the heating power of the single crystal furnace is gradually reduced step-by-step and shoulder rotation is started to perform when the crystal grows to reach the target diameter. By using the method, the growth cycle of the single crystal can be shortened by about 100 minutes and the success rate of necking is improved by 40 to 50 percent. Inaddition, the method has the advantages that necking temperature can be quickly found out, dislocation of the grown crystal is reduced, the growth cycle of single crystal is shortened and the contacttime between the silicon material and a quartz crucible is reduced, so that influence of silicon impurities is reduced as well as the success rate of necking and the quality of the single crystal areimproved.
