Abstract

A method is provided that includes sputtering a target located within a deposition chamber for a first time period to deposit a flux of target material on a production substrate located within the deposition chamber. The method further includes removing the production substrate from the deposition chamber, and performing a cleaning cycle within the deposition chamber. The cleaning cycle may include (1) placing a non-production object into the deposition chamber; either (2i) sputtering the target for a second time period, which is of shorter duration that the first time period, to deposit a flux of target material on the non-production object; or (2ii) simply flowing a gas into the deposition chamber for a second time period which is of shorter duration than the first time period; and (3) evacuating the deposition chamber. The cleaning cycle may be repeated one or more times. Apparatus are provided for performing the above-described method.
