ALD deposits one monolayer at a time by alternating between precursor and reactant exposures, achieving conformal coverage even in high-aspect-ratio features.
Molybdenum serves as both diffusion barrier and conductor, eliminating the separate barrier layer used in tungsten metallization and lowering resistance.
