The method concerns production of workpieces with coatings of a sufficient epitaxy quality, and is characterised by the fact that coating takes place by PECVD (plasma enhanced chemical vapour deposition) process with use of DC discharge. The claimed installation for implementation of the method includes a vacuum chamber (1), a cathode chamber (5) with at least one hot anode (7), a workpiece carrier (13) in the vacuum chamber, and an anode . The workpiece carrier is electrically insulated from the vacuum chamber.
