WebJan 1, 2003 · NIST is preparing to issue the next generation in its line of binary photomask linewidth standards. Called SRM 2059, it was developed for calibrating microscopes used to measure linewidths on photomasks, and consists of antireflecting chrome line and space patterns on a 6 inch quartz substrate (6 x 6 x 0.25 inches, or 15.2 x 15.2 x 0.635 cm). WebFIG. 2 is a schematic representation of a prior art binary photomask. FIG. 3 is a schematic representation of a binary mask of the present invention in which an energy-blocking layer is over-coated with a diamond-like carbon layer, the edges of the two layers being in register so that they together define the edges of a geometry being reproduced.
