   Short version - building-up memory chips (and other
   kinds) requires little holes between the layers to
   create electrical connections. Alas below a certain
   size and the holes can't be filled-up with conductive
   material properly ... it tends to just overcoat the
   top of the hole and nothing gets down the the layer
   below.
   It has now been found that introducing xenon to the
   manufacturing atmosphere helps prevent this, maybe
   physically 'coating' the walls of the hole. Using
   this, material CAN be reliably deposited in the
   hole from bottom-up.
   Xenon is expensive, but use per-batch can likely
   be optimized. It's also infinitely recyclable.
   Dual atomic-scale membranes might be able to
   concentrate xenon and only then would cyrogenic
   methods be needed for final purification.
