摘要:
A method for the electron beam deposition of a multicomponent evaporant to ensure a consistent layer quality with constant composition and thickness in a defined manner. The X-radiation emitted from the evaporant on the point of electron beam impingement is measured in situ, using the obtained signal as reference input to control the parameters of the evaporation process and therefore to control the deposition rate and material composition of the deposited layer. The method is used for the production of corrosion resistant, high-temperature resistant, hard-wearing or optical layers on, for example, strip steel or plastic film.

Certain non-optical characteristics and, in particular, mechanical characteristics are not measurable in situ in the industrial production of layers using plasma-assisted reactive electron beam vaporization, particularly if high demands are made on the hardness, wear resistance and barrier action, so as to be able to reproducibly apply the layers. The values of the optical layer characteristics are to be used as a control signal. In this method, immediately after the substrate has passed through the vaporizing zone, the reflection and/or transmission and absorption capacity are measured in the wavelength range .DELTA..sub.k =150 to 800 nm and from this are determined the refractive index and optical absorption coefficient. These determined values are compared with an experimentally determined desired value. A control signal obtained therefrom, in the case of a constant reactive gas partial pressure, controls the plasma and maintains constant the optical characteristics of the layer. The method is used in the vapor-deposition of wear-resistance, hard layers or barrier layers, e.g. of metal oxide on glass, plastic and other materials, e.g. in the building industry for facade glass and in the packaging industry.
