Cleaning compositions
This disclosure relates to a cleaning composition that contains 1) hydroxylamine, 2) an amino alcohol, 3) hexylene glycol, and 4) water.
Cleaning Composition For Semiconductor Substrates
Compositions and methods useful for removing residue and photoresist from a semiconductor substrate comprising: from about 5 to about 60% by wt. of water; from about 10 to about 90% by wt. of a water-miscible organic solvent; from about 5 to about 90% by wt. of at least one alkanolamine; from about 0.05 to about 20% by wt. of at least one polyfunctional organic acid; and from about 0.1 to about 10% by wt. of at least one phenol-type corrosion inhibitor, wherein the composition is substantially free of hydroxylamine.
COMPOSITIONS FOR REMOVING ETCH RESIDUES, METHODS OF USING AND USE THEREOF
This disclosed and claimed subject matter relates to a post etch residue cleaning compositions that include an alkanolamine having two or more or more than two alkanol groups, an alpha-hydroxy acid and water as well as methods for use thereof in microelectronics manufacturing.
Method for removing one or more of: coating, corrosion, salt from a surface
Embodiments of the present methods and solutions that operate to prepare a metal surface to be ready for coating or primer. The surface is operated on using mechanical or pressure impingement operation in conjunction with application of medium comprising dimethylethanolamine (DMEA) and water (DMEA diluted in water). Embodiments of the present invention can perform the wash or decontamination to leave a clean surface that provides excellent performance in durability and rust resistance after being coated or primed. Other cleaning chemicals if added may reduce the performance and interfere with the desired objective. Other surfaces are contemplated.
HIGH ALKALINE CLEANERS, CLEANING SYSTEMS AND METHODS OF USE FOR CLEANING ZERO TRANS FAT SOILS
The present disclosure relates to high alkaline cleaners, cleaning systems and methods for removing polymerized zero trans fat soils. The high alkaline cleaner of the present invention generally includes one or more alkaline wetting and saponifying agent(s), a chelating/sequestering system and a surface modifying-threshold agent system. In various embodiments, the cleaners may include, at least one cleaning agent comprising a surfactant or surfactant system and/or a solvent or solvent system and/or cleaning booster such as a peroxide or sulfite type additive. The cleaners may also include one or more components to modify the composition form and/or the application method in some embodiments. All components described above may also be optimized optionally, to provide emulsification of a composition (both as a usable product or a concentrate that can be diluted to form a usable product). The use of the high alkaline cleaner of the present invention has demonstrated enhanced cleaning characteristics especially at higher temperatures (100° F. to about 200° F.) but also shows enhanced cleaning at ambient temperatures.
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.
Cleaning compositions
This disclosure relates to a cleaning composition that contains 1) at least one redox agent; 2) at least one alkylsulfonic acid or a salt thereof, the alkylsulfonic acid containing an alkyl group substituted by OH or NH.sub.2; and 3) at least one aminoalcohol.
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.
Microelectronic Device Cleaning Composition
A composition for cleaning a microelectronic device substrate is provided. The composition is useful for cleaning in-process microelectronic device substrates possessing exposed cobalt, molybdenum, copper, molybdenum, tungsten, and dielectric surfaces. Also provided is a method for cleaning such devices and a kit comprising one or more of the components of the composition.
METHOD FOR REMOVING ONE OR MORE OF: COATING, CORROSION, SALT FROM A SURFACE
