Thin films
Thin Film Deposition
Thin film deposition techniques are used to deposit a wide variety of materials on the wafer surface. This films can be used for their electrical, electrochemical, thermal, piezoelectric, magnetic or mechanical properties. They are usually either selectively deposited (i.e. lift off) or selectively etched away after deposition to form patterned thin films. Commonly deposited layer thickness ranges between tens of nanometers to a few microns.
Numerous techniques exist for thin film deposition. Commonly used in micromachining are:
