Suitable for multi-layer sequential sputtering of two materials, the Q300T D Plus has two independent sputtering heads, which allows sequential sputtering of two metals without the need to break vacuum. The system is fully automated with user defined recipes controlling the pumping sequence, time, number of sputter cycles, and the current used during the process. Unlimited layers of varying thickness from two target materials can be sputtered sequentially by cycling between both targets.  When not in use the targets are shuttered for protection from contamination.
