One of the challenges facing in nanofabrication is to deposit dielectric films with thickness compared to the feature size under fabrication, typically in a range of nanometer, for the purposes such as gate dielectrics, surface passivation, diffusion barrier, charge storage gap, and etc. In addition, many applications use a variety of substrates that require deposition temperatures less than 200_0†2C without losing film qualities. In this work, we demonstrate the feasibility of using electron cyclotron resonance (ECR) plasma-enhanced CVD method to achieve ultra-thin (nanometer scale) dielectric thin films at temperatures less than 200_0†2C. In particular, Si3N4 films with thickness in sub-ten nanometer were successfully deposited at temperature
