    摘要: A memory device includes an active area protruding from a semiconductor substrate. A recess is formed in the active area. A field oxide layer is formed on the semiconductor substrate. A gate electrode extends across the active area while being overlapped with the recess. A gate insulation layer is interposed between the gate electrode and the active area. Source and drain areas are formed in the active area. The transistor structure above defines a recessed transistor structure if it is sectioned along a source-drain line and defines a Fin transistor structure if it is sectioned along a gate line. The transistor structure ensures sufficient data retention time and improves the current drivability while lowering the back bias dependency of a threshold voltage.

    摘要: A fin transistor is formed by forming a hard mask layer on a substrate having an active region and a field region. The hard mask layer is etched to expose the field region. A trench is formed by etching the exposed field region. The trench is filled with an SOG layer. The hard mask layer is removed to expose the active region. An epi-silicon layer is formed on the exposed active region. The SOG layer is then partially etched from the upper end of the trench, thus filling a lower portion of the trench. A HDP oxide layer is deposited on the etched SOG layer filling the trench, thereby forming a field oxide layer composed of the SOG layer and the HDP oxide. The HDP oxide layer in the field oxide layer is etched to expose both side surfaces of the epi-silicon layer. A gate is then formed on the epi-silicon layer of which both side surfaces are exposed and the field oxide layer.

    摘要: Disclosed is a method for forming a capacitor of a semiconductor device. In such a method, a mold insulating layer is formed on an insulating interlayer provided with a storage node plug, and the mold insulating layer is etched to form a hole through which the storage node plug is exposed. Next, a metal storage electrode with an interposed WN layer is formed on a hole surface including the exposed storage node plug and the mold insulating layer is removed. Finally, a dielectric layer and a plate electrode are formed in order on the metal storage electrode.

    摘要: Disclosed is a method for forming a capacitor of a semiconductor device, which can improve a leakage current characteristic in applying HfxAlyOz as a dielectric film. In such a method, HfxAlyOz thin films are deposited on a storage electrode to form an HfxAlyOz dielectric film and a plate electrode is formed on the dielectric film. The HfxAlyOz dielectric film consists of laminated HfxAlyOz thin films which are different in compositions of Hf and Al such that the lower HfxAlyOz thin film adjoining the storage electrode has a larger composition ratio of Al than that of Hf and the upper HfxAlyOz thin film has a larger composition ratio of Hf than that of Al, and the upper HfxAlyOz thin film is subjected to heat treatment under an oxygen atmosphere after its deposition.

    摘要: A method for manufacturing a semiconductor device is disclosed. The method includes the steps of defining a trench into a field region of a semiconductor substrate having an active region and the field region; partially filing the trench with a flowable insulation layer; completely filling the trench with an isolation structure by depositing a close-packed insulation layer on the flowable insulation layer in the trench; etching through a portion of the close-packed insulation layer and etching into a partial thickness of the flowable insulation layer of the insulation structure to expose a portion of the active region; cleaning the resultant substrate having the active region relatively projected; forming spacers on etched portions of the flowable insulation layer where bowing occurs during the cleaning step; and forming gates on the active region and the insulation structure to border the exposed portion of the active region.
