DESCRIPTION
Silicon single crystal refers to the crystal structure is completely consistent, defect-free single crystal silicon, has a wide range of applications in semiconductor manufacturing, solar cells, optoelectronics and other fields.
Silicon metal can be made of silicon single crystal, mainly because of its high purity, good crystallization, strong thermal stability and other characteristics. The following, we will introduce the principle and method of silicon metal manufacturing silicon single crystal from several aspects.
The purity of silicon metal is very high, generally can reach more than 99.999%. This high purity silicon metal can be prepared by chemical vapor deposition, physical vapor deposition, electrochemical deposition and other methods. These methods can effectively remove impurities and oxides in metallic silicon, so as to obtain very high purity silicon materials. This high purity metallic silicon can be crystallized at high temperatures to form single crystals of silicon.
The crystallinity of silicon metal is also one of the important factors in the manufacture of silicon single crystal. Silicon metal at high temperature can be crystallized into silicon single crystal, this is because silicon metal crystallization performance is very good, its lattice structure is very regular, ordered, no impurities and defects, can form a perfect crystal structure. At the same time, the crystal growth rate of silicon metal is relatively slow, which can avoid crystal defects and impurities caused by excessive crystal growth.
