Method of fabricating a flash memory device

Номер: US0007919369B2
Автор: Soo Jin Kim, KIM SOO JIN

In a method of fabricating a flash memory device, a lower capping conductive layer of a peri region is patterned. A step formed between a cell gate and a gate for a peri region transistor is decreased by controlling a target etch thickness of a hard mask. Thus, an impurity does not infiltrate into the bottom of the gate for the peri region transistor through a lost portion of a SAC nitride layer. Accordingly, a hump phenomenon of the transistor formed in the peri region can be improved. Furthermore, a leakage current characteristic of the transistor formed in the peri region can be improved.
