Abstract
The use of Atomic Layer Deposition (ALD) and Molecular Layer Deposition (MLD) applied to powders and intermediates of the MLCC fabrication process can provide significant advantages. Coating metal particles within a defined range of ALD cycles is shown to provide enhanced oxidation resistance. Surprisingly, a very thin ALD layer was found to substantially increase sintering temperature.
