The effect of … WebAtomic layer deposition (ALD) is a special type of chemical vapor deposition (CVD) technique that can grow uniformed thin films on a substrate through alternate self-limiting …
WebJan 30, 2004 · Abstract. Al 2 O 3 films were deposited by atomic layer deposition (ALD) at temperatures as low as 33 °C in a viscous-flow reactor using alternating exposures of Al (CH 3) 3 (trimethylaluminum [TMA]) and H 2 O. Low-temperature Al 2 O 3 ALD films have the potential to coat thermally fragile substrates such as organic, polymeric, or biological ... WebMolecular layer deposition (MLD) is a vapour phase thin film deposition technique based on self-limiting surface reactions carried out in a sequential manner. Essentially, MLD resembles the well established technique of atomic layer deposition (ALD) but, whereas ALD is limited to exclusively inorganic coatings, the precursor chemistry in MLD can use …
