WebOct 12, 2013 · CH 4 plasmas are often employed for hydrocarbon film deposition, 31 and thus can be invoked for sidewall passivation in plasma etching processes to generate anisotropic etch profiles. 21 Hydrocarbon deposition on the PR surface (132 nm) and sidewall (83 nm) is evident in Figures 1b and 2b. WebNov 1, 2024 · Etching was performed using an ICP RF power of 500 W, 300 V DC-bias voltage, and 0.67 Pa process pressure. As the CH 4 gas concentration increased from 0% to 75% CH 4, the etch rates of the copper films and SiO 2 masks gradually decreased. However, a polymer layer was deposited on the Conclusions rpm seafood greenhouses

WebEtch rates of various compound semiconductors in methane/hydrogen/argon versus (a) RIE self-bias voltage, (b) pressure, (c) concentration, and (d) temperature. The parameters were varied about 4 sccm CH4, 20 sccm H2, 10 sccm Ar, 75 mTorr, 500 Volts, and room temperature, except for (d), which was done at 10 mTorr without Ar. WebJun 4, 1998 · In general, etch rates diminished with quartz tube length. At the longer transport tube lengths (e.g., 125 cm), using a Teflon lining material strongly increases the etch rate for pure CF 4 /O 2 discharges as compared to the quartz. For discharges containing N 2, the etch rate is more than doubled.
