Abstract:
This invention provides a method for growing monocrystalline silicon by applying Czochralski method comprising forming a melt of silicon-containing materials in a crucible and pulling the melt for monocrystalline silicon growth, which is characterized by, the silicon-containing materials comprising a deuterium-implanted nitride-deposited silicon and a monocrystalline silicon, introducing a gas containing argon during formation of the melt, and, applying a magnetic field during the pulling step. This invention also provides a method for producing a wafer based on the above monocrystalline silicon.
