Declarations under Rule 4.17: of inventorship (Rule 4.17(iv)) Published: — with international search report (Art. 21(3)) W O 20 1717 / 8 168 Al (54) Title: HEAT TREATABLE ANTIREFLECTIVE GLASS SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME (57) : The invention concerns a method for manufacturing heat treatable antireflective glass substrates by ion implantation, comprising selecting a source gas of N2, 02, or Ar, ionizing the source gas so as to form a mixture of single charge and multicharge ions of Ar, N, or 0, forming a beam of single charge and multicharge ions of Ar, N, or 0 by accelerating with an acceleration voltage comprised between 15 kV and 60 kV and setting the ion dosage at a value comprised between 7,5 x 10 16 and 7,5 x 10 17 ions/cm 2 . The invention further concerns heat treatable and heat treated antireflective glass substrates comprising an area treated by ion implantation with a mixture of simple charge and multicharge ions according to this method.
