A method for manufacturing a semiconductor device using a salicide process, which includes forming a gate dielectric layer over a silicon substrate including a PMOS region and an NMOS region; forming a first silicon pattern in the NMOS region and a second silicon pattern in the PMOS region; forming a first metal layer that is in contact with the first silicon pattern and the exposed first portion of the silicon substrate; and forming a first gate, a first junction, a second gate, and a second junction by performing a heat treatment to silicify the respective first and second silicon patterns and the silicon substrate.

Method of manufacturing semiconductor device using salicide process

A method of fabricating a non-volatile memory device includes forming a tunneling layer and a conductive layer on a semiconductor substrate, and patterning the conductive layer, the tunneling layer, and the semiconductor substrate to form a conductive pattern, a tunneling pattern, and a trench in the semiconductor substrate. The method also includes filling the trench with a insulating material, and exposing a partial sidewall of the conductive pattern. The method further includes recessing the exposed partial sidewall of the conductive pattern in an inward direction to form a floating gate. The floating gate includes a base portion and a protruding portion having a width smaller than that of the base portion. The method also includes etching the insulating layer to form an isolation layer that exposes the base portion of the floating gate. Still further, the method includes forming a dielectric layer, that extends along the base and protruding portions of the floating gate, and a control gate that covers the base and protruding portions of the floating gate.
