An apparatus and method for depositing a carbon layer includes an arc discharge is formed between an electron source and an evaporation material by means of a first power supply device. The negative terminal of the first power supply device is connected in an electrically conducting manner to the electron source and the positive terminal of the first power supply device is connected in an electrically conducting manner to the evaporation material. A permanent magnet system and a solenoid coil are arranged in a rotationally symmetrical manner around the evaporation material. The evaporation material is formed as a graphite rod which is surrounded by at least one heat-insulating element at least on the rod end to be evaporated of the graphite rod.

Apparatus and method for depositing hard carbon layers

A method for producing a component is provided, where the component comprises a substrate, which emits at least one electromagnetic radiation in a first wavelength range and an electromagnetic radiation in a second wavelength range within one surface area. Electrodes can be formed within the surface area of the substrate; a first layer stack can be deposited, comprising at least one layer, which causes the emission of the electromagnetic radiation in the first wavelength range, and a cover layer, acting as the first counterelectrode, on the entire surface area; the first layer stack can be removed from a first partial surface area, which comprises at least one electrode; a second layer stack can be deposited, comprising at least one layer, which causes the emission of the electromagnetic radiation in the second wavelength range, and a second cover layer, acting as the counterelectrode, on the entire surface area.
