ALD

Atomic Layer Deposition ALD uses timed pulses of reactive precursors to encapsulate all exposed surfaces of a substrate for coating. It gets its name from the nature of these pulses, each of which deposits a single self-terminating layer.  It is a subclass of chemical vapour deposition (CVD). The coating can be controlled with atomic precision.
