WebJul 1, 2013 · Re-deposition is a non-volatile etching by-product in reactive ion etching systems that is well known to cause dirt on etching work. In this study, we propose a … WebThis deposition rate is highly dependent upon the energy invested per particle of gas mixture flowing through the glow discharge zone. For a given plasma reactor setup this is a function of several process parameters, including pressure, applied power, flow rate, and monomer species [ 13, 16, 18, 19, 41 ].
Sputtering only happens when the kinetic energy of the incoming particles is much higher than conventional thermal energies (≫ 1 eV). When done with direct current (DC sputtering), voltages of 3-5 kV are used. When done with alternating current (RF sputtering), frequencies are around the 14 MHz range. Surfaces of solids can be cleaned from contaminants by using physical sputtering in a vacuum. … WebFeb 14, 2024 · In this approach, CaO–CoO film is first deposited by rf-magnetron reactive cosputtering from metallic targets of Ca and Co. Second, the as-deposited film is reactively annealed under O2 gas flow to form the final phase of CaxCoO2.
