  • Growth-orientation of crystals by raster scanning electron beam
    Patent number: 4187126
    Abstract: A method of grain-orienting the crystal structure of a layer of semiconductor material by application of a raster scanning electron beam to a layer of polycrystalline semiconductor material which has been previously formed on a substrate, such as by sputter-plasma film deposition. The method comprises electron beam lithography computer-applied to the crystal growth and orientation of a polycrystalline thin sheet of silicon or other semiconductor material.
