摘要： The present invention relates to a wet etching composition including a sulfonic acid, a phosphonic acid, a phosphinic acid or a mixture of any two or more thereof, and a fluoride, and to a process of selectively etching oxides relative to nitrides, high-nitrogen content silicon oxynitride, metal, silicon or silicide. The process includes providing a substrate comprising oxide and one or more of nitride, high-nitrogen content silicon oxynitride, metal, silicon or silicide in which the oxide is to be etched; applying to the substrate for a time sufficient to remove a desired quantity of oxide from the substrate the etching composition; and removing the etching composition, in which the oxide is removed selectively.

摘要： On a mis au point un procédé de préparation d'ammoniaque quaternaire de pureté améliorée. Dans un mode de réalisation, cette invention concerne un procédé de préparation d'ammoniaque quaternaire à partir des sels d'ammonium quaternaire correspondants dans une cellule électrolytique, comprenant un compartiment d'analyte contenant une anode, et un compartiment de catholyte contenant une cathode et de l'eau. Lesdits compartiments d'anolyte et de catholyte sont séparés l'un de l'autre par une membrane d'échange de cations. Ledit procédé consiste à: (a) prévoir le catholyte avec une cathode en zinc, cadmium, étain, plomb ou des alliages de ceux-ci, mercure ou amalgame de mercure, (b) charger une solution aqueuse contenant un sel d'ammonium quaternaire dans le compartiment d'analyte, (c) faire passer un courant dans la cellule d'électrolyse pour produire de l'ammoniaque quaternaire dans le compartiement de catholyte, et (d) récupérer l'ammoniaque quaternaire du compartiment de catholyte.
