PROCEDE DE DEPOT DE COUCHES SUR UN SUBSTRAT VERRIER PAR PECVD A FAIBLE PRESSION

L'invention concerne un procédé de production de films d'oxydes, de nitrures ou d'oxynitrures de métaux ou semi-conducteurs sur un substrat, par la méthode de PECVD. The invention relates to a method for producing metal or semiconductor oxide, nitride or oxynitride films on a substrate, by means of the PECVD method, including the steps that involve: (i) having a low-pressure PECVD device including at least one plasma source that includes at least one electrode connected to an AC, DC, or drawn DC generator for depositing said films on the substrate; and (ii) applying electrical power to the plasma source and applying, on the substrate, an oxide film gas precursor made of metal or semiconductor nitrides or oxynitrides and a reactive gas made of oxygen, oxygen derivatives, or nitrogen derivatives. The invention also relates to metal or semiconductor oxide, nitride, or oxynitride films obtained by the method.
