Abstract:
A stacked substrate is produced using an apparatus including an injector head device. Production includes the steps of providing an injector head device comprising a gas bearing pressure arrangement and injecting bearing gas against opposite substrate surfaces, to balance the substrate without support in a conveying plane in the injector head device. The following steps are performed iteratively: contacting opposite substrate surfaces with a first precursor gas; and with a second precursor gas, first and second precursor gases supplied in first and second deposition spaces are arranged opposite and facing respective sides of the substrate; establishing relative motion between the deposition space and the substrate in the conveying plane; and providing at least one of a reactant gas, plasma, laser-generated radiation, and/or ultraviolet radiation, in any or both reactant spaces for reacting any of the first and second precursor gas after deposition on at least part of the substrate surface.
Abstract:
An injector head for atomic layer deposition on a substrate, comprising a plurality of bars coupled to a connection unit. The bars have side walls with a spacer profile, respectively stacked against side walls of a neighbouring bar to form a plurality of stacked bars. The bars comprise slots extending over a length of the bar in communication with a respective slot in the connection unit. A flow path is defined through the bar with a relatively low friction factor to form a respective precursor drain; reactant drain or barrier gas drain. The spacer profiles define slits extending between adjacent bars in communication with a respective slot in the connection unit. A further flow path is formed along the bar with a relatively high friction factor, to form a respective precursor gas supply; reactant gas supply or flow barrier.
