Patent ID: 7989290

Claim:
A method of forming an electronic device, the method comprising: forming a dielectric on a substrate; after forming the dielectric, forming conductive rhodium-based nanoparticles on the formed dielectric including forming the rhodium in the conductive rhodium-based nanoparticles with a deposition time selected to attain a predetermined retention loss property, the conductive rhodium-based nanoparticles formed by a plasma-assisted deposition process such that each conductive rhodium-based nanoparticle is isolated from the other conductive rhodium-based nanoparticles; and after forming the conductive rhodium-based nanoparticles, forming a capping dielectric on and contacting the formed conductive rhodium-based nanoparticles, the capping dielectric contacting the dielectric such that the capping dielectric isolates the conductive rhodium-based nanoparticles from conductive elements, wherein the conductive rhodium-based nanoparticles are configured as charge traps.
