Depositing ultra-thin layer at the nanoscale requires Atomic Layer Deposition ( ALD) technology, which allows materials to be deposited one atomic layer at a 

Atomic layer deposition (ALD) is a type of chemical vapor deposition (CVD) where the reactions are limited to the surface of the object being coated. Instead of flowing two or more gasses into the chamber and letting them react on or near the surface of the substrate as in CVD, in ALD the individual chemical components are introduced to the deposition chamber one at a time.

Based on sequential, self-limiting reactions, ALD offers exceptional conformality on high-aspect ratio structures, thickness control at the Angstrom level, and tunable film composition. Atomic Layer Deposition The secret to gaining improved control was to split the deposition process into half-reactions, each of which can be well-controlled. The ALD process starts by flooding the reaction chamber with a precursor that coats (or “adsorbs” onto) the exposed surface of the wafer. Research and Development in Atomic Layer Deposition for Particles and Powders Careful attention is needed, even with trivial tasks when developing ALD processes. This is why Forge Nano is offering its Prometheus R&D tools to eliminate the biggest challenge heard by customers, inconsistent results that come from poorly-adapted wafer ALD tools.
