Atomic layer deposition apparatus for depositing a film in a continuous fashion. The apparatus includes a downwardly sloping process tunnel, extending in a transport direction and bounded by at least two tunnel walls. Both walls are provided with a plurality of gas injection channels, whereby the gas injection channels in at least one of the walls, viewed in the transport direction, are connected successively to a first precursor gas source, a purge gas source, a second precursor gas source and a purge gas source respectively, so as to create a series of tunnel segments that -in use - comprise successive zones containing a first precursor gas, a purge gas, a second precursor gas and a purge gas, respectively. The downward slope of the process tunnel enables gravity to drive the floatingly supported substrates through the successive segments, causing the atomic layer deposition of a film onto the substrates. |
