Theoretical study of the decomposition mechanism of sf6 gas/Cu

Sep 10, 2018 · Among all the decomposition pathways, the favorable decomposition reactions of SF 6 + Cu mixtures are found: reaction R1 contributes more than reaction R2 in the decomposition of SF 6 + Cu mixtures due to its lower energy released; reaction R3 is dominant in the decomposition of SF 5 + Cu other than multi-step reactions; the chemical processes of SF 4 + Cu → IM x → TS y (where x stands for 9, 10 and 13, and y denotes 7, 8 and 9) may play the same role in SF 4 + Cu decomposition, but theGet price

Selective Dry Etching of GaN Over AlGaN in BCL3/Sulfr hexafluoride Mixtures

Inductively coupled plasma (ICP) etching of GaN with high selectivity over Al. 22 Ga. 78 N in BCl 3 /SF 6 mixtures has been studied. Selectivity and surface morphology were investigated over a wide range of pressures (3.75 37.5mTorr), RF powers (30 120 W), ICP powers (100 400 W), and SF 6 /BCl 3 ratios (0.1 0.7). Higher pressures, lower dc biases, and higher SF 4 /BCl 3 ratios increased the GaN to AlGaN selectivity.Get price
