摘要: In one aspect, non-conformal layers are formed by variations of plasma enhanced atomic layer deposition, where one or more of pulse duration, separation, RF power on-time, reactant concentration, pressure and electrode spacing are varied from true self-saturating reactions to operate in a depletion-effect mode. Deposition thus takes place close to the substrate surface but is controlled to terminate after reaching a specified distance into openings (e.g., deep DRAM trenches, pores, etc.). Reactor configurations that are suited to such modulation include showerhead, in situ plasma reactors, particularly with adjustable electrode spacing. In another aspect, alternately and sequentially contacting a substrate, the substrate including openings, with at least two different reactants, wherein an under-saturated dose of at least one of the reactants has been predetermined and the under-saturated dose is provided uniformly across the substrate surface, deposits a film that less than fully covers surfaces of the openings, leading to depletion effects in less accessible regions on the substrate surface

摘要: Methods of forming a metal carbide film are provided. In some embodiments, methods for forming a metal carbide film in an atomic layer deposition (ALD) type process comprise alternately and sequentially contacting a substrate in a reaction space with vapor phase pulses of a metal compound and one or more plasma-excited species of a carbon-containing compound. In other embodiments, methods of forming a metal carbide film in a chemical vapor deposition (CVD) type process comprise simultaneously contacting a substrate in a reaction space with a metal compound and one or more plasma-excited species of a carbon-containing compound. The substrate is further exposed to a reducing agent. The reducing agent removes impurities, including halogen atoms and/or oxygen atoms.

摘要: Methods of forming a metal carbide film are provided. In some embodiments, a substrate is exposed to alternating pulses of a transition metal species and plasma-excited argon. The transition metal species is reacted with a carbon species to deposit a metal carbide film. The substrate is exposed to the carbon species simultaneously with the transition metal species, or the substrate is exposed to the carbon species in pulses temporally separated from the pulses of the transition metal species. In some embodiments, the carbon species and the transition metal species form parts of the same precursor compound, e.g., a metal organic compound.
