1. Laboratory: A Typical Evaporation Process

2. - Open evaporator.

3. - Remove wafer holder.

4. - This is where the wafers will be during the evaporation process.

5. - Remove the bell jar.

6. - Prepare metal: e. g., use metal wire.

7. - The metal will be placed in a "basket".

8. - Some evaporators use a "coil" instead of a "basket".

9. - Both metal and basket/coil should be cleaned.

10. - They should then be dried in the dehydration oven.

11. - The basket/coil should be installed between the two electrodes,
and the metal placed inside the basket or around the coil.

12. - Move shutter to cover the filament.

13. - Put on the bell jar.

14. - Carefully load the wafers onto the wafer holder.

15. - One of the wafers may be a "test" wafer for measuring the metal layer thickness.

16. - Replace the wafer holder back on top of the bell jar.

17. - Place the cover back onto the bell jar.

18. - Lower pressure ( ~ 10-6 Torr ).

19. - Heat the filament to evaporate the metal.

20. - Cool and remove wafers.

21. - The test wafer allows measurement of film thickness.
