  • Silicon manufacture
    Patent number: 3977934
    Abstract: A method of producing monocrystalline semiconductor material in web form from a source of polycrystalline semiconductor material. The source material is heated to form a molten zone on the end thereof, which is contacted by a thermal profile shaping member formed from the same type of semiconductor material as the semiconductor material to be produced. A monocrystalline seed crystal of the shape of the web desired then contacts the molten end of the source material near the shaping member and is withdrawn therefrom as monocrystalline semiconductor material forms on the end thereof.
