Abstract
A method of fabricating a non-volatile memory is provided. A substrate having a trench therein for forming a trench device is provided. Then, a doped metal silicide layer is formed on the substrate in the trench. A heating process is performed to form a source/drain area in the substrate under the doped metal silicide layer. Thereafter, a first conductive layer is formed on the doped metal silicide layer to fill up the trench.
