Abstract
Some embodiments include methods of forming charge-trapping zones. The methods may include forming nanoparticles, transferring the nanoparticles to a liquid to form a dispersion, forming an aerosol from the dispersion, and then directing the aerosol onto a substrate to form charge-trapping centers comprising the nanoparticles. The charge-trapping zones may be incorporated into flash memory cells.
