Abstract:
1. A method of forming flash memory devices from nanoparticles comprising: providing a source of conductive nanoparticles consisting essentially of spherical particles having an average diameter of between 1 nm and 20 nm with a standard deviation of number average diameter of less than 15% and a symmetrical shape; providing a transistor base; providing a first electrically insulating layer over a surface of the transistor base to provide an electrically insulating surface distal from the transistor base; depositing the conductive spherical nanoparticles to the surface of the transistor base in a first distribution of the spherical nanoparticles; applying a field to the conductive spherical nanoparticles on the surface of the transistor base that applies a force to the spherical particles; rearranging the spherical conductive nanoparticles on the surface of the transistor base by the force from the field to form a second distribution of conductive spherical nanoparticles on the surface of the transistor that is more ordered or more patterned than the first distribution of conductive spherical nanoparticles; and overlaying a second electrically insulating layer over the second distribution of conductive spherical nanoparticles.
