Abstract

Causes of reproducibility problem in thin film deposition using magnetron sputtering have been identified. To remedy this problem, one must calibrate deposition rate after installation of a new target or magnetron and should repeat such calibrations as frequently as possible in order to obtain films with reproducible properties. For magnetrons used in our laboratory to be
in working condition, the transverse magnetic field strength on the surface of the magnetron should be about 50 mT or more.
