Webion implantation fits well into silicon planar technology. The oxide layers used for masking against diffusion can be used to mask against the ion beam. Furthermore, ion implantation can be performed through thin passivating layers (e.g. SiO 2, Si 3 N 4 ), or using photoresist masks. Webmetals can form, which via ion or photon-assisted processes can be desorbed from the surface at etching rates of a few nm/min. Photoresist Processing Requirements Vertical Resist Sidewalls For the steepest possible resist profi les, a high-contrast, photoresist, as well as process parameters opti-mised for high contrast are required, i.e.
