“…Muitos destes processos são ainda pouco conhecidos do ponto de vista teórico, e muito do conhecimento atual a respeito desses sistemas é puramente empírico. O crescente interesse na compreensão dos fenômenos envolvidos motivou numerosos estudos [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] sobre a química de misturas de CF 4 /O 2 e SF 6 /O 2 .…”

“…The improved understanding of plasma properties has led to the development of accurate mathematical models for various plasma etching processes which can be used to compute reactor con"gurations that reduce the etching nonuniformity (e.g. Park & Economou, 1990;Park & Economou, 1991;Bushman, Edgar, & Trachtenberg, 1997;Venkatesan, Trachtenberg, & Edgar, 1987). Such studies have revealed that the use of a showerhead arrangement to introduce the precursor gas into the reaction chamber, signi"cantly reduces the radial etching nonuniformity.…”

“…As discussed in that work, models for the plasma chemistry of SF 6 /O 2 and CF 4 /O 2 mixtures have been extensively investigated by different research groups [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] . These processes are extremely complex to be modelled and solved, considering all the homogeneous processes in the gas phase and the heterogeneous processes occurring at the gas-solid interface 20 .…”
