In plasma depositing of metal into a polymer, small increases in substrate temperature will dramatically slow down the rate of polymer formation whereas the simultaneous metal deposition rate into the polymer matrix is unaffected for the same temperature excursion. As a result, the metal-to-polymer ratio in the film can be changed, keeping everything else constant in the plasma. This is considered a great advantage considering the complexity in the subsequent plasma chemistry that would result from most other plasma parameter changes. The table below reports actual data of the ratio of polymer-to-metal as determined by E.S.C.A. analysis. The particular example chosen to validate the above claim is gold metal clusters dispersed in the polymer matrix. In this case the film analysis is straightforward since the E.S.C.A.
