<p>Apparatus (10) for coating a surface of an article (14) with a thin film polymer layer by plasma deposition, the apparatus comprising: a plurality of processing chambers (12a, 12b, 12c....12n) into each of which one or more articles can be placed; means (18, 19, 20, 21, 22) for supplying an active species to said processing chambers for forming a plasma in said chambers; a plurality of induction means (24) associated with respective processing chambers, each induction means being operable to induce an electrical field internally of an associated processing chamber for forming a plasma when said active species is supplied thereto so that a surface of said article can be coated with a thin film polymer layer by plasma deposition; means (26) for providing a time varying electric current in the induction means; and pressure control means (28) for selectively controlling pressure in said processing chambers such that pressure in any one or more of said chambers can be controlled independently of pressure in other of said chambers.</p> |
