ATOMIC-LAYER DEPOSITION SUBSTRATE
A substrate for fluidic levitation processing includes a moveable substrate and a levitation stabilizing structure located on the moveable substrate. The levitation stabilizing structure defines an enclosed interior impingement area of the moveable substrate that stabilizes lateral displacement of the moveable substrate during fluidic levitation processing.

a moveable substrate; and
a levitation stabilizing structure located on the moveable substrate defining an enclosed interior impingement area of the moveable substrate that stabilizes lateral displacement of the moveable substrate during fluidic levitation processing.
2 . The substrate of claim 1 , further comprising one or more atomic thin-film layers on the moveable substrate in the interior impingement area.
3 . The substrate of claim 1 , wherein an additional structure is located within the enclosed interior impingement area of the levitation stabilizing structure.
4 . The substrate of claim 3 , wherein the levitation stabilizing structure has a height greater than the height of the additional structure.
5 . The substrate of claim 3 , wherein the additional structure is a solid or forms a closed curve.
6 . The substrate of claim 3 , further comprising a thin-film layer located on the moveable substrate in the interior impingement area, wherein at least a portion of the additional structure is formed on the thin-film layer.
7 . The substrate of claim 1 , further comprising a patterned thin-film layer.
8 . The substrate of claim 1 , further comprising a thin-film layer located on the moveable substrate in the interior impingement area, wherein at least a portion of the levitation stabilizing structure is formed on the thin-film layer.
