20120187336 | CONDITIONING COMPOSITIONS FOR SOLAR CELLS - Method of using improved compositions for conditioning silicon surfaces during the manufacture of photovoltaic devices. Used for removing particles, organic contamination, and unwanted metals from these surfaces. Also used for removing a thin layer of silicon as required for damage removal or texturing. These conditioning and surface preparation compositions comprise one or more water soluble strongly basic components capable of producing a pH greater than 10, one or more water soluble organic amines, one or more chelating agents, and water. | 07-26-2012 |
20100018550 | CLEANING COMPOSITIONS WITH VERY LOW DIELECTRIC ETCH RATES - Aqueous cleaning compositions comprising a tertiary organic amine, an organic acid, a non-metallic fluoride salt, a corrosion inhibitor, e.g., ascorbic acid or its derivatives alone or in combination, balance water, effective to remove plasma processing residues (sidewall polymer) which include metal-organic complexes and/or inorganic salts, oxides, hydroxides or complexes which form films or residues either alone or in combination with the organic polymer resins. These compositions clean effectively at low temperatures without etching metal or dielectric layers, including low-κ dielectric materials. | 01-28-2010 |
20090120457 | COMPOSITIONS AND METHOD FOR REMOVING COATINGS AND PREPARATION OF SURFACES FOR USE IN METAL FINISHING, AND MANUFACTURING OF ELECTRONIC AND MICROELECTRONIC DEVICES - Improved cleaning compositions for removing particles, organic contamination, photoresist, post-ash residue, coatings, and other materials from metal and silicon surfaces including substrates present during the manufacture of integrated circuits, liquid crystal displays, and photovoltaic devices. The cleaning and surface preparation compositions comprise one or more water soluble strongly basic components, one or more water soluble organic amines, one or more water soluble oxidizing agents, balance water. Optional components can include corrosion inhibitors, surfactants and chelating agents. | 05-14-2009 |
