Coating
Method to deposit material on a surface. The most common methods are
evaporation and sputtering. Evaporation is achieved in a vacuum chamber in which the evaporation is done
thermally by heating the material above its melting point. Sputtering is done with a gas plasma. Ions from the plasma
are accelerated towards the target
surface releasing atoms
from the target
which condense on the sample surface (and everywhere else). The advantage of sputtering is a lower temperature
compared to thermal evaporation.
