What is Deposition?
Deposition is the transformation of vapors into solids, frequently used to grow solid thin film and powder materials.
Two types of deposition:
Physical vapour deposition.
Chemical vapour deposition
WHAT IS PLASMA ?
The temperature of the ions and neutral particles is usually less than one-hundred degrees Celsius, the energy of the electrons in such a plasma corresponds to a temp-erature of some 10 000 degrees Celsius!
Thus they serve as highly reactive tools for powerful but gentle applications without consuming great energy.
