    摘要: Integrated circuit memory devices having highly integrated SOI memory cells therein include an SOI substrate having a semiconductor active layer therein. A first trench isolation region is also provided. The first trench isolation region extends into and partitions the semiconductor active layer into first and second active regions. These first and second active regions are preferably electrically isolated from each other by the first trench isolation region. First and second access transistors are provided in the first and second active regions, respectively, and a first electrically insulating layer is provided on the SOI substrate. A first bit line is also provided at a first level. The first bit line is electrically connected to a first source/drain region of the first access transistor by a first bit line contact. This first bit line contact extends through the first electrically insulating layer and contacts the first source/drain region of the first access transistor. A second electrically insulating layer is also provided on the first bit line, opposite said first electrically insulating layer and a second bit line is provided on the second electrically insulating layer at a second level above the first level. The second bit line is electrically connected to a first source/drain region of the second access transistor by a second bit line contact which extends through the first and second electrically insulating layers and contacts the first source/drain region of the second access transistor. Higher integration densities can be achieved by dividing the active layer into electrically isolated active regions and then forming bit lines at different levels which are electrically connected to access transistors within these isolated active regions.

    摘要: In a method of manufacturing a non-volatile memory device, a conductive structure is formed on a substrate. The conductive structure includes a tunnel oxide pattern, a first conductive pattern, a pad oxide pattern and a hard mask pattern. A trench is formed on the substrate using the conductive structure as an etching mask. An inner oxide layer is formed on an inner wall of the trench and sidewalls of the tunnel oxide pattern and the first conductive pattern. The inner oxide layer is cured, thereby forming a silicon nitride layer on the inner oxide layer. A device isolation pattern is formed in the trench, and the hard mask pattern and the pad oxide pattern are removed from the substrate. A dielectric layer and a second conductive pattern are formed on the substrate. Accordingly, the silicon nitride layer prevents hydrogen (H) atoms from leaking into the device isolation pattern.

    摘要: Methods of fabricating a semiconductor device having multi-gate insulation layers and semiconductor devices fabricated thereby are provided. The method includes forming a pad insulation layer and an initial high voltage gate insulation layer on a first region and a second region of a semiconductor substrate respectively. The initial high voltage gate insulation layer is formed to be thicker than the pad insulation layer. A first isolation layer that penetrates the pad insulation layer and is buried in the semiconductor substrate is formed to define a first active region in the first region, and a second isolation layer that penetrates the initial high voltage gate insulation layer and is buried in the semiconductor substrate is formed to define a second active region in the second region. The pad insulation layer is then removed to expose the first active region. A low voltage gate insulation layer is formed on the exposed first active region. Accordingly, it can minimize a depth of recessed regions (dent regions) to be formed at edge regions of the first isolation layer during removal of the pad insulation layer, and it can prevent dent regions from being formed at edge regions of the second isolation layer.
