چکیده انگلیسی
In order to understand the erosion behavior of oxide ceramics during their exposure to fluorocarbon plasma, the thin films of AlF3, YF3, Al2O3, Y2O3 and SiO2 were deposited on silicon and then their surfaces were irradiated with Ar ions of different kinetic energies. When we measured the relative sputtering rates, fluoride was sputtered faster than oxide with strong dependency on its chemistry, while the sputtering rates of oxides were nearly identical. The fact that AlF3 was sputtered a few times faster than YF3 is consistent with previously observed faster etch rate in Al2O3 than in Y2O3 under fluorocarbon plasma. These results support that erosion of ceramics under fluorocarbon plasma occurs by a physical removal process of fluorinated surfaces which were simultaneously induced by their interaction with the fluorocarbon plasma. Based on these results, implications for plasma resistance of oxide ceramics and production of contamination particles in the silicon wafer processing chamber under fluorocarbon plasma will be discussed based on their thermal properties and a numerical simulation.
