Invention relates to corrosion-inhibiting compositions and the process of using said compositions to protect metal from corrosion. The compositions comprise of sulfonates, a carboxylic-sulfonic acid metal complex, antioxidants, fluorinated copolymers, hydrophobic silanes and siloxane additives and solvent.

A method for improving both the microscopic and macroscopic uniformity of materials during etching is disclosed herein. These improvements may be accomplished through the formation and dissolution of thin, self-limiting layers on the material surface by the use of wet atomic layer etching (ALE) techniques. For etching of polycrystalline materials, these self-limiting reactions can be used to prevent this roughening of the surface during etching. Thus, as disclosed herein, a wet ALE process uses sequential, self-limiting reactions to first modify the surface layer of a material and then selectively remove the modified layer.

The present invention discloses a method for improving the blood compatibility of a material surface by using a controllable grafting technique. The method involves placing a monomer NVP, an RAFT reagent and a solvent acetonitrile in a container, adding an initiator AIBN, mixing the same uniformly, removing oxygen with liquid nitrogen, making the same react in an oil bath; after polymerization, adding liquid nitrogen to quench and stop the reaction, thus obtaining PVP-COOH; mixing the PVP-COOH with DCC and NHS; adding dry dichloromethane to the mixture in a nitrogen atmosphere, adding mercaptoethylamine, and making the same react in darkness at room temperature; obtaining a crude sample; dissolving the crude sample in water, and performing dialysis with deoxygenated water in darkness, and then obtaining HS-PVP by freeze-drying. An AuS bond chemisorption method is used to controllably graft an anti-protein high-molecular polymer onto an Au surface.

A surface treatment solution includes a fluoride source; a first solvent; and a water transforming agent to transform water produced during wafer surface treatment into a second solvent, which can be the same as, or different from, the first solvent. The solution can be used, for example, in surface preparation for wafers having a backend including an electrical interconnect that includes aluminum or an aluminum alloy.
