Abstract :
Size-controlled nanocrystals (Si NCs) in floating gate MOS structure have been fabricated by thermal annealing of Si-rich SiNx layers with high ratio of Si/N. High resolution transmission electronic microscopy (HRTEM) reveals the size of Si NCs can be controlled by varying the thickness of Si-rich SiNx layer. Based on the analysis of XPS and Raman measurement, the relation between the size of Si NCs and the thickness of Si-rich SiNx is discussed.
