Abstract
Disclosed is apparatus for atomic layer deposition including a frame, an injector head with longitudinal slots supplying gases to deposition spaces confined by the longitudinal slots and a substrate. The slots are transverse to a movement in a first direction of the substrate, a subframe suspending the injector head; a movable carrier supporting the substrate for movement in the first direction; and gas pads at the subframe outside the injector head between the subframe and the moveable carrier, bearing the subframe on the carrier for the movement in the first direction. Actuators suspend the injector head from the subframe, and a control device connected to the actuators controls the actuators to adjust a working distance between a reference plane of the injector head and the surface of the substrate corresponding to a predetermined distance and to adjust an orientation of the injector head corresponding to an orientation of the substrate.
