Area selective atomic layer deposition method and tool
patent
The present disclosure concerns an atomie layer deposition device for area-selective deposition of a target material layer onto a deposition area of a substrate surface further comprising a non-deposition area. In use the substrate is conveyed along a plurality of deposition and separator spaces including at least two gas separator spaces provided with at least a separator gas inlet and a separator drain for, in use exposing the substrate to a separator gas flow. Wherein at least one of the gas separator spaces farms a combined separator-inhibitor gas flow comprising a separator gas and inhibitor moieties. The inhibitor moieties selectively adhering to the non-deposition area to form an inhibition layer reducing adsorption of precursor moieties. In a preferred embodiment the device includes a back-etching space to increase selectivity of the deposition process.
