  • Method for manufacturing a micro-electronic component having an electrically conductive tip of doped silicon
    Patent number: 5516404
    Abstract: A method for manufacturing an electrically conductive tip for field emission cathodes of vacuum electronic components includes forming the tip of doped silicon by molecular beam epitaxy of doped silicon through an opening of a mask and onto a substrate of monocrystalline silicon. The molecular beam epitaxy also produces a doped silicon layer on the surface of the mask.
