  • Patent number: 10723652
    Abstract: Described herein are various antimicrobial soda lime glass articles that have improved resistance to discoloration when exposed to harsh conditions, including manufacturing conditions. The improved antimicrobial glass articles described herein generally include a SLG substrate that has a thickness, t; a compressive stress layer of about 0.15*t or greater; and an antimicrobial agent-containing region having an antimicrobial agent and a thickness less than the thickness of the compressive stress layer. Roughly 2 to 20 microns of the primary surfaces of the glass substrate can be removed prior to development of the compressive stress and antimicrobial agent-containing region. In some aspects, prior-annealed and tempered, or prior-annealed, SLG is employed as the substrate. In some aspects, the substrate includes tin at one surface. The improved SLG substrates experience substantially no discoloration when exposed to harsh conditions. Methods of making and using the glass articles are also described.

  • Publication number: 20100311244
    Abstract: The present invention discloses a double-exposure method comprising a first lithography process and a second lithography process. Between the first and the second lithography process, coat Resolution Enhancement Lithography Assisted by Chemical Shrink (RELACS) material on the first photoresist pattern, promote thermal crosslinking reaction at the interface between the RELACS materials and the first photoresist pattern; afterwards, remove the RELACS material which does not crosslink with the first photoresist pattern. This method not only realizes higher lithography resolution, but also avoids the adverse effects of the second exposure on the first photoresist pattern in double-exposure technology.
