Thin Film Deposition
HV Evaporator
Plassys MEB 550S
The MEB 550S electron beam evaporator with fully automated control. For reduced pumping time the machine has a load lock and is capable of processing substrates up to 4″. The substrate holder can be adjusted in an angel to the source with an accuracy of 0.01°. It also can rotate around it’s own axis. For cleaning/etching substrates the evaporator has an ion gun with which an O2 or Ar/O2 plasma can be created. The accuracy of the deposition rate is determined by an oscillating crystal and is up to 0.01nm/s.
Available Metals: Al, Au, Pd, Pt, Ti, Cr, Co, V, Nb

UHV Evaporator
Plassys MEB 550S2
The MEB 550 S2 is a UHV type evaporator with three chambers. This computer controlled evaporation tool dedicated for fabrication of quantum devices. It has a high precision tilting/rotating sample holder for shadow evaporation, and oxygen gas inlet for oxidation of tunnel barriers. The source chamber is cryo pumped and separated from the sample chamber by a gate valve. The sample chamber is turbo pumped, and is equipped with an ion gun for sample pre-cleaning and etching.
Allowed metals: Al, Nb, Ti
- Source chamber with a linear 4x 15 cc UHV ebeam source
- Treatment chamber above the source chamber
- Lateral Sample load lock for a 4″ substrate
- Possibility for in-situ oxidation
