ABSTRACTMOS memory devices containing semiconductor nanocrystals have drawn considerable attention recently, due to their advantages when compared to the conventional memories. Only little work has been done on memory devices containing metal nanoparticles.We describe the fabrication of a novel MOS device with embedded Pt nanoparticles in the HfO2 / SiO2 interface of a MOS device. Using as control oxide, a high-k dielectric, our device has a great degree of scalability. The fabricated nanoparticles are very small (about 5 nm) and have high density. High frequency C-V measurements demonstrate that this device operates as a memory device.
