  • Floating Zone method

    Using thermal energy on the semiconductor bar to create a molten region, then weld the single crystal seed. Adjust the temperature while this molten zone is moved slowly along the crystal bar’s the other end. The molten region melts impure solid at its forward edge and leaves a wake of purer material solidified behind it as it moves through the ingot. The single crystal orientation is the same as the seed crystal.
