Abstract

Metal/high-k dielectric core shell nanocrystal memory capacitor was demonstrated. This kind of MOS memory shows good performance in charge storage capacity, programming and erasing speed. By using a self-assembled Block Co-Polymer, Co/HfO2 core shell nanocrystals were well arrayed and showed uniform dot size and inter distance between dots. Compared with traditional metal nanocrystal fabrication process with E-Beam Evaporation followed by RTA (Rapid Thermal Annealing), core shell nanocrystal memory prepared by Block Co-Polymer produces a wide memory window of 8.4V at the ±12 V voltage sweep. Co/HfO2 core shell nanocrystals prepared by low-temperature Block Co-polymer process ensure high reliability of the devices.
