Embodiment Construction
[0037] Such as figure 1 As shown, the present invention includes the following steps: 1) grinding the impurity-containing part of the bulk silicon raw material; putting the polished silicon raw material into a clear water tank for rinsing, and observing the surface of the silicon raw material after rinsing;
[0038] 2) According to observation: put the silicon raw material containing a small amount of impurities or even no impurities into the lye pool for soaking, and wash the remaining impurities and glue residue on the surface of the silicon raw material; repeat the steps for the silicon raw material containing a large amount of impurities 1) Operation;
[0039] 3) Soak the silicon raw material in the lye pool in step 2) for 15-25 minutes, and take out the silicon raw material soaked in the lye pool and observe (in this example, the immersion time of the silicon raw material is 20 minutes) ;
[0040] 4) According to observation: Put the silicon raw materials with bright surf...
