Cleaning formulation for removing residues on surfaces
This disclosure relates to a cleaning composition that contains 1) at least one redox agent; 2) at least one first chelating agent, the first chelating agent being a polyaminopolycarboxylic acid; 3) at least one metal corrosion inhibitor, the metal corrosion inhibitor being a substituted or unsubstituted benzotriazole; 4) at least one pH adjusting agent, the pH adjusting agent being a base free of a metal ion; and 5) water. This disclosure also relates to a method of using the above composition for cleaning a semiconductor substrate.
Post CMP Cleaning Compositions
In general, the invention provides high pH cleaning compositions for dielectric surfaces such as PETEOS, SiO.sub.2, thermal oxide, silicon nitride, silicon, etc. The compositions of the invention afford superior surface wetting, dispersion of particles and organic residues, and prevents redeposition and re-agglomeration of the dispersed residue during cleaning to afford superior cleaning and low defectivity.
Reduced mist alkaline cleaner via the use of alkali soluble emulsion polymers
Alkaline sprayable aqueous compositions for cleaning, sanitizing and disinfecting are disclosed. In particular, the sprayable compositions include an alkali soluble emulsion polymer, an alkalinity source, a foaming agent, and water. Beneficially, the sprayable cleaning compositions have reduced misting and are environmentally safe for users to apply. Further the compositions exhibit less running on non-horizontal surfaces than acrylamide-based compositions.
ALKALINE CLEANING COMPOSITIONS COMPRISING AN ALKYLAMINO HYDROXY ACID AND/OR SECONDARY AMINE AND METHODS OF REDUCING METAL CORROSION
The invention relates to compositions, methods of manufacture, and methods for reducing metal corrosion during alkaline cleaning. In particular, the method employs an alkylamino hydroxy acid, secondary amine, or combination thereof in alkaline cleaning of hard surfaces.
Cleaning Compositions
This disclosure relates to a cleaning composition that contains 1) at least one redox agent; 2) at least one chelating agent, the chelating agent being a polyaminopolycarboxylic acid; 3) at least one corrosion inhibitor, the corrosion inhibitor being a substituted or unsubstituted benzotriazole; 4) at least one sulfonic acid; and 5) water.
SYSTEMS AND METHODS FOR CLEANING A COOLING TOWER FILL WITH A CHEMICAL GEL
A process of using a chemical gel cleaning formulation to clean a cooling tower fill, comprising the steps of applying a pre-rinse fluid to the fill; applying the chemical gel cleaning formulation to the fill, wherein the chemical gel cleaning formulation includes glycerin, at least one polysaccharide, at least one corrosion inhibitor, at least one surfactant, and at least one acid; applying a descaling fluid to the fill; applying a neutralizer solution to the fill to neutralize the pH of residual fluid on the fill surface; and rinsing the fill with a rinsing fluid to remove residual chemical gel cleaning formulation and descaling fluid, residual neutralizer solution, and dissolved deposits from the fill.
Pressed, self-solidifying, solid cleaning compositions and methods of making them
The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.
CLEANING COMPOSITION FOR POST-ETCH OR POST ASH RESIDUE REMOVAL FROM A SEMICONDUCTOR SUBSTRATE AND CORRESPONDING MANUFACTURING PROCESS
A cleaning composition for post-etch or post ash residue removal from a substrate used in semiconductor industry and a corresponding use of said cleaning composition is described. Further described is a process for the manufacture of a semiconductor device from a semiconductor substrate, comprising the step of post-etch or post ash residue removal from a substrate by contacting the substrate with a cleaning composition according to the invention.
