Abstract :
In this study, Si/SiO/sub 2/ superlattice materials were fabricated by radio frequency (RF) Si sputtering and reactive oxide deposition. The samples were prepared with different numbers of bi-layers (Si/SiO/sub 2/ layers). The deposited materials were crystallized by furnace annealing or rapid thermal annealing (RTA). The microstructures of the materials were observed by transmission electron microscopy (TEM). The crystallization of the materials was studied by high resolution TEM and Raman spectroscopy. The relationship between the crystallization and processing conditions is discussed.
