Kuech (Elsevier, 2015). doi: FOR TEACHING AND SCHOLARLY USE ONLY - DO NOT DISTRIBUTE 1 Abstract Atomic Layer Deposition (ALD), also referred to historically as Atomic Layer epitaxy (ALE), is a vapor-phase Deposition technique for preparing ultrathin films with precise growth control.

induced evaporation or sputtering by energetic ion bom-bardment. The method of CVD, on the other hand, in-volves chemical reactions. These chemical reactions take place by volatile precursor molecules that decompose at the surface leaving a thin film and volatile by-products. The chemical reactions are thermally driven, most fre-

SPUTTERING Instead of using heat to eject material from a source, we can bombard them with high speed particles. The sputtering gas bombards the target and sputters off the material we would like to deposit. Once ejected, these atoms (or molecules) can travel to a substrate and deposit as a film.
