  • Photoresist ashing process using carbon tetrafluoride gas

    A low-damage photoresist ashing process was developed for the fabrication of thin-film transistor liquid-crystal displays (TFT-LCDs). This process utilizes a downflow plasma using a carbon tetrafluoride/oxygen (CF 4 /O 2) gas mixture at room temperature.Although this process simultaneously achieves a high ashing rate and a low etching rate for an underlying amorphous silicon (a-Si:H) film

  • Evaluation of SF6-alternative gas C5-PFK based on arc

    Aug 30, 2017SF 6 has been widely used in the electrical industry for decades due to its good insulation properties and rapid heat recovery capability. However, it has a very high global warming potential (GWP), so for decades research has focused on SF 6-alternative gases [1–3].Recently, a new alternative named C5-PFK (C5-perfluoroketone) has attracted a lot of interest because of its good insulation
