Isotropic Plasma Etching of SiO2 Films - Russian Microelectronics

Abstract. The isotropic etching of SiO 2 with an SF 6 –O 2 plasma is studied experimentally. It is shown that the key factors in the process are the total and partial pressures of SF 6 and O 2 and the RF power. A smoothed-down edge profile of contact windows is obtained if SF 6 and O 2 are mixed in a ratio of 1 : 10 to 1 : 5.Get price

The decomposition products of sulfur hexafluoride (Sulfr hexafluoride

Abstract. Sulfur hexafluoride (SF 6) is being widely used in a variety of industrial processes, commercial products and scientific fields due to its unique characteristics such as relatively low toxicity, extreme inertness and high dielectrics. However, the chemically stable gas is one of the most potent greenhouse gases (GHGs) that cause significantly global warming, and has been, thus, blanketed into the Kyoto Protocol.Get price
