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
