1. Device for forming thin dielectric layers at the surface of at least one solid body (16), of the type comprising a tube (2) through which a current of reactive gas flows and which contains the body to be treated (16), means for generating a plasma within the tube (2), means for heating the zone of the tube in which the body to be treated (16) is situated, the latter being brought to an electrical potential of polarity opposite to that of the ions of the plasma in relation to that of an electrode (24) likewise situated within the tube (2), characterized in that the means for generating the plasma are situated at one end of the tube, thus defining a plasma generation zone (14), in that the zone in which the body to be treated (16) is situated is separated from the plasma generation zone (14) by an intermediate space (22) dimensioned in such a manner as to prevent the contamination of the body to be treated (16) by particles generated by cathode sputtering in the zone of generation of the plasma (14), and in that the electrode (24) is situated on the side opposite to the plasma generation zone (14) in relation to the body to be treated (16). |
