Technology Description:

This system will be decomissioned in the end of 2018 and will be replaced with a new evaporator.

An e-beam evaporator is used to deposit single or multilayer thinfilms of metals, oxides, magnetic materials and dielectrics. An electron beam is sweeped over the target surface transforming target atoms into gaseous phase which precipitates into solid form coating the chamber. This takes place under high vacuum (~10-7 Torr) enabling the atoms to evaporate freely in the chamber. The deposition thickness is controlled by a quartz crystal monitor.Minimum controlled deposition is ~1 nm and maximum is several micrometers. The deposition rate can be varied from ~0.1 nm/s to ~20 nm/s. Deposition thickness is uniform up to sample sizes of 50 mm. For larger samples the sample stage can be rotated during deposition.

Materials allowed: 

Everything which is not considered as contaminating within NanoLab rules, sample size can’t exceed 101.6 mm (4”) in diameter and 10 mm in thickness.
