 Evaporation technique

ITO fully sublimes. The films are deposited by reactive and non-reactive electron beam evaporation using Cu-crucibles with Mo-liners or thermal evaporation using Mo-boats cover. But these evaporation techniques are difficult because indium oxide and tin oxide will evaporate per their individual vapor pressures, so sputtering is preferred for depositing thin films of ITO.
