  • Epitaxially coated silicon wafer with 110 orientation and method for producing it
    Patent number: 8133318
    Abstract: An epitaxially coated silicon wafer comprises a plane surface misoriented relative to a {110} crystal plane, wherein the <110> direction of the single silicon crystal is tilted away by the angle ? from the normal to the wafer surface and the projection of the tilted <110> direction forms an angle ? with the direction <?110> in the wafer, and ? is given by 0???3° and 45°???90°, as well as for all symmetrically equivalent directions.
    Type: Grant
