Vapour-phase depositionLaajuus (3 ECTS)

Objective

The student can describe how coatings are formed from the vapour phase. He or she can define the factors affecting the coating properties. He or she can outline the most common vapour-phase deposition methods. The student can present the potential applications and the limitations of vapour-phase deposition. The student shall also adopt basics of vacuum technology.
