Flycut rusty surface4/2/2023 ![]() This paper presents a new cleaning process using boron-doped diamond (BDD) film anode electrochemical oxidation for metallic contaminants on polished silicon wafer surfaces. SEMICONDUCTOR TECHNOLOGY A new cleaning process for the metallic contaminants on a post-CMP wafer's surfaceīaohong, Gao Yuling, Liu Chenwei, Wang Yadong, Zhu Shengli, Wang Qiang, Zhou Baimei, Tan The metals included in this review are silver (Ag), aluminum (Al), goldmore » (Au), copper (Cu), iron (Fe), iridium (Ir), molybdenum (Mo), niobium (Nb), nickel (Ni), palladium (Pd), platinum (Pt), rhodium (Rh), ruthenium (Ru), tantalum (Ta), and tungsten (W)« less ![]() The uncertainties are based in part on the error distribution for all measured work functions in the literature, which is included here. These results are used to construct a recommended value of the work function for each surface examined, along with an uncertainty estimate for that value. The tables presented include all results found for low-index crystal faces except cases that were known to be contaminated surfaces. Worth, Eli H.Ī critical review of the experimental literature for measurements of the work functions of clean metal surfaces of single-crystals is presented. Recommended values of clean metal surface work functionsĭOE Office of Scientific and Technical Information (OSTI.GOV)ĭerry, Gregory N., E-mail: Kern, Megan E. The solvent composition is nonhazardous so that when it is used to clean the surfaces of radioactive materials the waste in the form of paper or cloth wipes, lab coats and the like used in the cleaning operation is not considered to be mixed waste composed of a hazardous solvent and a radioactive material. and 2 to 25 volume percent of a polar solvent having a flash point sufficiently high so as to provide the solvent composition with a minimum flash point of at least 140.degree. The solvent composition consists essentially of a blend of nonpolar aliphatic hydrocarbon solvent having a minimum flash point of about 140.degree. Thompson, Lisa M.Ī solvent composition for displacing greasy and oily contaminants as well as water and/or aqueous residue from metallic surfaces, especially surfaces of radioactive materials so that such surfaces can be wiped clean of the displaced contaminants, water and/or aqueous residue. The solvent composition consists essentially of a blend of nonpolar aliphatic hydrocarbon solvent having a minimum flash point of about 140 F and 2 to 25 volume percent of a polar solvent having a flash point sufficiently high so as to provide the solvent composition with a minimum flash point of at least 140 F.

Nonhazardous solvent composition and method for cleaning metal surfaces In general, the salt content of thc cleaning agents ranged from 10 to 90%, preferably from 10 to 40% by weight and the balance of the composition comprises nitric acid of any strength from extremely dilute up to concentrated strength. The cleaning agents of the invention consist of aqueous nitric acid and an amhydrous nitrate salt of a metal which is lower in the electromotive series than the element of the deposit to be removed. Little, T.H.Ĭleaning fluids for removing deposits from metal surfaces are described. Metal surfaces are cleaned by contacting the surface with the cleaning solvent and then passivated by contact with aqueous solutions of citric acid or sodium nitrite or a combination of the two. nickle-iron alloys, contains sulfamic acid, citric acid, a solvent for hydrocarbon residues, and a surfactant.
