MODERATELY ALKALINE CLEANING COMPOSITIONS FOR PROTEINACEOUS AND FATTY SOIL REMOVAL AT LOW TEMPERATURES
The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120 F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.
CERIA REMOVAL COMPOSITIONS
The present invention generally relates to a removal composition and process, particularly useful for cleaning ceria particles and CMP contaminants from microelectronic devices having said particles and CMP contaminants thereon, in particular microelectronic devices having PETEOS, Silicon Nitride, and Poly-Si substrates. In one aspect, the invention provides treatment of the microelectronic substrate having ceria particles thereon utilizing complexing agents free of Sulfur and Phosphorous atoms.
IMPROVED METHOD FOR NICKEL-FREE PHOSPHATING METAL SURFACES
The present invention relates to a method for substantially nickel-free phosphating of a metallic surface, wherein a metallic surface is treated one after the other with the following compositions: i) with an alkaline, aqueous cleaner composition which comprises at least one water-soluble silicate, and ii) with an acidic, aqueous, substantially nickel-free phosphating composition which comprises zinc ions, manganese ions and phosphate ions.
The invention also relates to the above cleaner composition itself and also to a metallic surface phosphate-coated by the above method, and to the use of said surface.
