  • Method of selective growth of microcrystalline silicon
    Patent number: 4004954
    Abstract: An array of microcrystalline silicon pads for a vidicon target is selectively grown, by the hydrogen reduction of silicon tetrachloride, along surface portions of a silicon wafer exposed through openings in an overlying silicon dioxide layer. The method disclosed avoids the spurious irregular growth of silicon on the silicon dioxide layer between the adjacent silicon pads.
