Abstract Nanocrystal (NC) floating gate flash memory is considered to be one of the most promising candidates to replace conventional highly doped polysilicon floating gate flash memory technology widely used today. [1] Metal NCs is more desirable compared to its semiconductors to work as charge storage storage node, because metals usually have large work function and can be engineered down to 1 nm without decreasing potential well depth. [2, 3] However, most metal NCs are easily oxidized and diffuse into the surrounding dielectric under high temperature process conditions, resulting in bad NC-dielectric interface quality and the degradation of the memory performance.[4] In this paper, for the first time, we present an approach using Ruthenium (Ru) NC buried in HfO matrix to work as charge storage nodes, which can create a robust NC- high K dielectric interface. Combined with some advantages of Ruthenium, good memory device performance can be achieved.
