1. A method for applying a coating on substrate, the method comprising:

  • placing the substrate into a chamber;

    impinging an evaporant source in the chamber with a beam to generate an evaporated vapor cloud in the chamber; and

    presenting a carrier gas stream to the chamber to disperse the evaporated vapor cloud;

    deflecting the evaporated vapor cloud being moved by the carrier gas stream, wherein the deflecting is done with at least one vapor cloud modifier that disrupts a flow of the carrier gas stream that prevents an area of the substrate from being coated, and wherein the evaporated vapor cloud at least partially coats at the substrate.
