Abstract
A method for producing a memory device with nanoparticles, including steps of: a) forming, in a substrate based on at least one semi-conductor, source and drain regions, and at least one first dielectric on at least one zone of the substrate arranged between the source and drain regions and intended to form a channel of the memory device, b) depositing of at least one ionic liquid that is an organic salt or mixture of organic salts in a liquid state, wherein nanoparticles of at least one electrically conductive material are suspended in the ionic liquid, said ionic liquid covering at least said first dielectric, c) forming a deposition of said nanoparticles at least on said first dielectric, d) removing the ionic liquid remaining on the first dielectric, and e) forming at least one second dielectric and at least one control gate on at least one part of the nanoparticles deposited on the first dielectric.
