Abstract

1494790 Sputter etching KERNFORSCHUNG mbH GES FUER 8 May 1975 [12 July 1974] 19310/75 Heading B3V [Also in Divisions B6 and C7] An apparatus for gas or cathodic ion etching a metallographic sample 26 and for coating a workpiece 61 by sputtering of the sample 26 comprises a housing 1, a holder 29 for holding the sample 26 to be etched, a focusing means 42 for the ionized or sputtered particles to or from the sample surface adjustably positioned within an electrically insulating sleeve 46 between the holder 29 and an electrode 11 and a holder for the workpiece 61 to be coated between the focusing means 42 and the electrode 11. The housing 1 is made of glass and is connected to vacuum pumps (7, 14), (Fig. 1, not shown). The holder 29 comprises a plate 30 which is mounted on a water cooled pipe 31 and which mounts a spring 41 for pressing the sample 26 to be etched, e.g. gold and also comprising the source of coating material against an inwardly directed flange 57 on a sleeve 35. The temperature of the sample 26 is monitored by thermocouples. When the sample 26 is to be cathodically etched, the housing 1 is filled through an inlet 15 with argon, xenon and/or krypton. When the sample 26 is to be gas etched, the housing 1 is filled with oxygen, carbon dioxide and/or nitrogen and the sample 26 is anodically connected so that negative gas ions accumulate on, and thereby etch, the sample surface. The ions are focused on to the sample 26 by an apertured disc 42 adjustably mounted in the sleeve 46. The upper part 49 of the sleeve 46 houses samples 61 to be coated which are held between clamping elements 51, 52.
