Nanocrystal formation using atomic layer deposition
Nanocrystal structures formed using atomic layer deposition (ald) processes are useful in the formation of integrated circuits such as memory devices. Rather than continuing the ald process until a continuous layer is formed, the ald process is halted prematurely to leave a discontinuous formation of nanocrystals which are then capped by a different material, thus forming a layer with a discontinuous portion and a bulk portion.
