WebJan 11, 2024 · Test Data of etching SiO2 with CHF3/CF4. ICP#2: 0.5Pa, 50/900W, CHF3/CF4=10/30 sccm, time=210 sec. Date. WebFeb 28, 2011 · The etch behaviour of Al2O3 was studied in Ar, CHF3/Ar, CF4/O2 and Cl2 low pressure RIE plasmas. The influence of dc self-bias voltage, wafer temperature, gas flow and pressure on the Al2O3 etch behaviour was investigated. This was compared with the etch behaviour of SiO2, Mo, Au and Si under the same conditions. It was found that … surgical timeliness - report viewer va.gov
