Abstract

La présente invention concerne un matériau de dépôt en phase vapeur qui permet de former une sous-couche capable de former uniformément une couche hydrofuge et oléofuge comprenant un condensat d'un composé contenant du fluor comportant un groupe silyle réactif, et qui permet de supprimer la variation de la composition de sous-couche entre des échantillons lorsqu'une pluralité de substrats ayant une sous-couche sur ceux-ci sont préparés. La présente invention concerne un matériau de dépôt en phase vapeur qui est composé de particules contenant un oxyde contenant : du silicium ; et au moins un élément I choisi dans le groupe constitué d'éléments du groupe 1, d'éléments du groupe 2, d'éléments du groupe 13, d'éléments du groupe 15 et d'éléments de métaux de transition dans la table périodique. Le rapport en masse de particules ayant une taille de particule de 0,5 à 22,4 mm est de 90 % en masse ou plus par rapport à la masse totale de l'ensemble des particules.
