  • Publication number: 20120187336
    Abstract: 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.

  • Patent number: 7922823
    Abstract: Compositions useful in microelectronic device manufacturing for surface preparation and/or cleaning of wafer substrates such as microelectronic device precursor structures. The compositions can be employed for processing of wafers that have, or are intended to be further processed to include, copper metallization, e.g., in operations such as surface preparation, pre-plating cleaning, post-etching cleaning, and post-chemical mechanical polishing cleaning of microelectronic device wafers. The compositions contain (i) alkanolamine, (ii) quaternary ammonium hydroxide and (iii) a complexing agent, and are storage-stable, as well as non-darkening and degradation-resistant in exposure to oxygen.

  • Publication number: 20100018550
    Abstract: 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-? dielectric materials.
