In the present work, we produced and study the reactive magnetron sputtering plasma in Ar+O2 ambient using a solid Zn target as sputter source. We evaluate the electron temperature, electron density and ion density using Langmuir probe measurement as a function of O2 flow rate and working pressure. We found that the electron temperature increased spontaneously with the oxygen flow rate. The electron temperature was almost doubled when O2 flow rate increased from 0 sccm to 10 sccm. The electron and ion densities increased with the oxygen flow rate between 0 sccm and 5 sccm. However, after 5 sccm of O2 flow rate which is approximately 11% of O2/(O2+Ar) flow rate ratio the electron density decreased drastically. This is due to the electron attachment and the production of negative ion species in Ar+O2 plasma environment. In addition, we found that the ion flux increase monotonically with the O2 flow rate thus will increase the ion bombardment effect on the deposited thin film and eventually damage the thin film. Our experimental results suggest that the O2 flow rate and the working pressure would have a significant influence on ion bombardment effect on deposited thin film. 2014-04-09T07:26:13Z 2014-04-09T07:26:13Z 2014 Article Advanced Materials Research, vol.832, 2014, pages 344-349 1662-8985 http://dspace.unimap.edu.my:80/dspace/handle/123456789/33563 http://www.scientific.net/AMR.832.344 10.4028/www.scientific.net/AMR.832.344 en Trans Tech Publications |
