Darc anti reflective coating
An antireflective, antiglare or anti-reflection (AR) coating is a type of optical coating applied to the surface of lenses, other optical elements, and photovoltaic cells to reduce reflection. In typical imaging systems, this improves the efficiency since less light is lost due to reflection. In complex systems such as cameras, binoculars, telescopes, and microscopes the reduction in reflections also impro… WebDielectric anti-reflective coating is conformal silane-based plasma deposited thin film. CVD DARC is implemented into production line only recently due to the maturity of this antireflective coating film quality and the need of the critical dimension control. CVD DARC can be used for severe topology film stacks, however, for lower RC

However, these reflectivity values are achieved only for …
WebDec 4, 2024 · Anti-reflective coating (also called "AR coating" or "anti-glare coating") improves vision, reduces eye strain and makes your eyeglasses look more attractive. These benefits are due to the ability of AR coating to virtually eliminate reflections from the front and back surfaces of your eyeglass lenses. WebUsed alone or in conjunction with Applied Materials' DARC (Dielectric Anti-Reflective Coating) film, this cost-effective, litho-enabling film offers high etch selectivity for polysilicon, nitride, and oxide; excellent CD control; and less LER.
