WebMay 1, 1998 · In this study, we thoroughly investigated the reactive ion etching mechanism of RuO 2 film in oxygen plasma with the addition of CF 4, Cl 2, and N 2. The etch rate of RuO 2 was examined as functions of flow rates of input gases, substrate temperature, DC bias applied to the substrate, and pressure. WebTwo reactive ion etching (RIE) processes were studied to show the relative etch selectivity between SiO2 and Si using two ﬂuorocarbon gases, CF4 and CHF3. Results show that CHF3 gives better selectivity (16:1) over CF4 (1.2 :1). On the other hand, the etch rate of SiO2 of CF4 is approximately 52.8 nm/min, faster than CHF3 (32.4 nm/min).

Webhigher etching rate. Dry Etching Technologies Plasma etching is dominated by chemical erosion. In this way Si or SiO 2 is etched usually with chlorinated and ﬂ uorinated hydrocarbons isotropic and very material selectively. With sputter etching (ion milling), the material is eroded physically by inert gas ions accelerated on the substrate. WebFeb 23, 2009 · Processing of these materials, in particular wet and dry etching, has proven to be extremely difficult due to their inert chemical nature. We report electron cyclotron resonance (ECR) etch rates for GaN, InN, AlN, In{sub (x)}Ga{sub (1-x)}Ni and In{sub (x)}Al{sub (1-x)}N as a function of temperature, rf-power, pressure, and microwave power. Webters. Etch rate, etch profile and surface smoothness have been investigated as a function of CF 4 flow rate, ICP power and work pressure.
