摘要 |
A source for feeding one or more gaseous precursors onto a surface of a substrate and an arrangement for processing the substrate by way of subjecting the surface of the substrate to alternately repetitive surface reactions of the precursors, the source including a gas feed member for feeding at least one or more precursors onto the surface of the substrate. The gas feed member is adapted rotatable about a rotation axis, the rotation axis being arranged to extend substantially parallel to the surface of the substrate. |
