Abstract

A promising charge trapping film with crystal embedded material is proposed for future electronic devices. Instead of conventional high-vacuum and expensive tool, this technique adopts very cheaper process of sol-gel spin-coating for fabrication of thin film material in the charge trapping flash memory (CTFM). The crystal from spinodal phase separation is observed for sol-gel thin film at 900 C annealing, and is strongly related to the thickness of the spin-coated thin film. The morphology of the crystal from the ethanol solvent system is in the isolated form, while from 2-propanol solvent is in the interconnected structure. The sol-gel-derived CTFM from ethanol exhibits the better memory performance of retention times for
