You are watching the sputtering of CoFe and Permalloy on a 3 inch Si wafer. The first faint plasma is the CoFe sputtering. When the CoFe gun shuts off the screen goes dark and the Permalloy gun is turned on. The plasma from the Permalloy deposition follows the path of the magnetic field.

In magnetron sputtering with a suitable magnetic field configuration it is also possible to control the microstructure, chemical and phase composition of the growing film. Besides balanced discharges, two types of unbalancements are possible: type I and type II. In type I, the plasma that is not strongly confined on the target, does not interact [...]
