Atomic Layer Deposition (ALD) Systems
What is Atomic Layer Deposition?
Atomic Layer Deposition (ALD) is a thin-film deposition process that deposits materials one atomic layer at a time using sequential, self-limiting chemical reactions. Unlike conventional CVD processes, ALD provides atomic-scale thickness control, exceptional conformality over complex three-dimensional structures, and highly uniform thin films across wafers and large-area substrates.
Because each deposition cycle is self-limiting, ALD enables unmatched precision, repeatability, and film quality for advanced thin-film manufacturing.
