Web17 sep. 2010 · Photoresist can mask ion implantation, an obvious advantage iover thermal diffusion which requires an oxide mask. Masking layers for ion implantation have to be substantially thicker than projected ranges, to ensure that the ions in the tail of distribution do not penetrate the mask. 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.
