Project Reports sf6 Treatment process

grinding process, the plasma stress relief process which uses SF6 gas is carried out in order to remove the damaged lay-er. After the plasma stress relief process, the spin coating of the photo resist and photolithography process are conduct-ed for the patterning. Then the wafer is cut by plasma dicing process which uses SF6 and O2 mixed gas.

  • Sulfur Hexafluoride (SF6) Plasma Treatment of Medical Grade

    Here, the surface of medical-grade PMMA has been fluorinated by sulphur hexafluoride (SF 6) plasma treatment to increase surface hydrophobicity thus improving the material lifetime in optical applications. Hydrophobic properties of the treated PMMA were investigated by means of contact angle measurements, while chemical modification was assessed by X-ray Photoelectron Spectroscopy (XPS) and Attenuated Total Reflectance Fourier Transform Infrared (ATR/FTIR) spectroscopy.

  • Plasma Etching Behavior of SF6 Plasma Pre-Treatment Sputter

    Yttrium oxyfluoride (YOF) protective materials were fabricated on sputter-deposited yttrium oxide (Y 2 O 3) by high-density (sulfur fluoride) SF 6 plasma irradiation. The structures, compositions, and fluorocarbon-plasma etching behaviors of these films were systematically characterized by various techniques. After exposure to SF 6 plasma, the Y 2 O 3 film surface was fluorinated significantly to form a YOF film with an approximate average thickness of 30 nm.

  • Orange/Red Photoluminescence Enhancement Upon SF6 Plasma

    Abstract. Although the origin and possible mechanisms for green and yellow emission from different zinc oxide (ZnO) forms have been extensively investigated, the same for red/orange PL emission from ZnO nanorods (nR) remains largely unaddressed. In this work, vertically aligned zinc oxide nanorods arrays (ZnO nR) were produced using hydrothermal process followed by plasma treatment in argon/sulfur hexafluoride (Ar/SF 6) gas mixture for different time.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of SF6can impact the climate. The electric power industry uses roughly 80 percent of all SF6 produced worldwide. Ideally, none of this gas would b...
