Platinum deposition

Platinum can be deposited by e-beam evaporation or sputtering. In the chart below you can compare the different deposition equipment.

Comment As of August 2018, Pt has not yet been deposited in the Temescal. Please contact the Thin Film group to develop a process.

* If depositing a total of more than 600 nm, please write to metal@danchip.dtu.dk well in advance to ensure that enough material is present.
