Abstract:
A web of a polymer film (1) is coated with an oxide layer, in particular with an SiO x barrier layer, by transporting the web with the aid of a rotatable drum (12) through a plurality of flame bands, which are directed in a radial direction from above against the circumferential surface of the drum, which extend at a distance from each other across the width of the web being supported and transported on this circumferential surface, and which are fed with a gas mixture comprising a combustible gas an oxidant and a silicon containing compound. Therein the circumferential surface of the rotatable drum is cooled to a predetermined temperature and the web is transported through the area of the tip of the inner flame region. Polymer films with barrier layers produced in the named way have at small layer thicknesses of less than 10 nm very good barrier properties. In addition, the process being carried out at ambient pressure can be carried out with simple equipment and, if required, in a continuous roll-to-roll or in-line process.
Abstract:
A sputtering target includes an outer target tube (90), an inner support tube (54) of rectangular cross-sectional shape supporting a magnet carrier extending along substantially the entire length of the inner support tube; and a water cooling circuit including at least one passageway within said inner support tube with an inlet at one end thereof adapted to receive cooling water from an external source, at least one outlet aperture at an opposite end thereof opening to a chamber radially between the inner support tube and the outer target tube; and at least one cooling water outlet at the one end of the inner support tube .
