Details of the methods used for precious material billing:
EVA 600 : Au / Ag
Thermal evaporation
- First, users have to order a tube “Gold grains – 6 grammes” or “Silver grains – 4 grammes” with the help of the user interface
- Unit price of the tube is fixed each month and is available with the user interface (Rates / Consumables)
A few numbers:
- Average weight of a gold grain = 0.15g
- Average gold consumption in EVA 600 : 0.015g/nm
- 1 gold grain => 80 Å – 120 Å
- Note : Don’t forget the gold consumption before opening the shutter(preevaporation)
E-beam evaporation
- Unit for billing : nm
- Deposition parameters for billing :
- td = thickness measured by the Crystal
- tf = fixed thickness for pre-evaporation
