    摘要: The present invention relates to a method of fabricating a flash memory device and includes forming an air-gap having a low dielectric constant between word lines and floating gates. Further, a tungsten nitride (WN) layer is formed on sidewalls of a tungsten (W) layer for a control gate. Hence, the cross section of the control gate that is finally formed can be increased while preventing abnormal oxidization of the tungsten layer in a subsequent annealing process. The method of the present invention can improve interference between neighboring word lines and, thus improve the reliability of a device. Accordingly, a robust high-speed device can be implemented.

    摘要: In one aspect of the inventive method, a tunnel insulating film, a first conductive layer, and an isolation mask pattern are formed over a semiconductor substrate. The first conductive layer and the tunnel insulating film are patterned along the isolation mask pattern. A trench is formed in the semiconductor substrate. The trench is gap filled with a first insulating film. A polishing process is performed in order to expose the first conductive layer. A height of the first insulating film is lowered. The first conductive layer on the first insulating film is gap-filled with a second insulating film.

    摘要: A method of manufacturing semiconductor devices includes forming a trench in a predetermined region of a substrate. A first insulating layer and a second insulating layer are formed on a entire surface so that the trench is gap-filled. The first and second insulating layers are polished until a top surface of the substrate is exposed. A wet etch process of a low selectivity is performed, so that a portion of the first insulating layer remains on sides of the trench while stripping the second insulating layer. A third insulating layer is formed on the entire surface, so that the trench is gap-filled, thereby forming an isolation structure.
