    摘要: A semiconductor device includes a gate structure on a channel region of a semiconductor substrate adjacent to a source/drain region therein and a surface insulation layer directly on the source/drain region of the substrate adjacent to the gate structure. The device further includes a spacer on a sidewall of the gate structure adjacent to the source/drain region. A portion of the surface insulation layer adjacent the gate structure is sandwiched between the substrate and the spacer. An interface between the surface insulation layer and the source/drain region includes a plurality of interfacial states. Portions of the source/drain region immediately adjacent the interface define a carrier accumulation layer having a greater carrier concentration than other portions thereof. The carrier accumulation layer extends along the interface under the spacer. Related methods are also discussed.

    摘要: A method of forming a trench device isolation structure, wherein, after forming a trench in a predetermined area of a semiconductor substrate, a lower isolation pattern, an upper liner pattern, and an upper isolation pattern are sequentially formed to fill the trench. A lower device isolation layer is formed on an entire surface of the semiconductor substrate, and then etched to form the lower isolation pattern so that a top surface of the lower isolation pattern is lower than a top surface of the semiconductor substrate. An upper liner layer and an upper device isolation layer are formed on the entire surface of the semiconductor substrate including the lower isolation pattern, and then etched to form the upper liner pattern. As a result, the upper liner pattern covers the top surface of the lower isolation pattern and surrounds the bottom and the sidewall of the upper isolation pattern.

    摘要: Methods of forming trench isolation regions include the steps of forming a trench masking layer comprising a first material (e.g., polysilicon) on a semiconductor substrate and then etching a trench in the semiconductor substrate, using the trench masking layer as etching mask. A trench nitride layer comprising a second material different from the first material is then formed on a sidewall of the trench and on a sidewall of the trench masking layer. The trench is then filled with a trench insulating material (e.g., USG). The trench masking layer is then removed by selectively etching the trench masking layer with an etchant that selectively etches the first material at a higher rate than the second material. This step of removing the trench masking layer results in exposure of a protruding portion of the trench nitride layer but does not cause the trench nitride layer to become recessed. The trench insulating material and the trench nitride layer are then etched back to define the trench isolation region.

    摘要: The present invention is directed toward a structure and method by which trench isolation for a wide trench and a narrow trench formed in first and second regions of a substrate may be achieved without formation of a void in an isolation layer, a groove exposing an isolation layer, or an electrical bridge between gates in a subsequent process. A lower isolation layer is formed on the substrate in a first and second trench. The lower isolation layer is patterned to fill a lower region of the first trench, and an upper isolation pattern is formed to fill the second trench and a remainder of the first trench. An aspect ratio of first trench is reduced, thereby preventing the occurrence of a void in the upper isolation layer, or a gap between the upper isolation layer and the substrate.

    摘要: A method of forming a trench isolation structure prevents a nitride liner from being over-etched, i.e., prevents the so-called dent phenomenon from occurring. An etching mask pattern is formed on a semiconductor substrate. A trench is formed in the substrate by using the etching mask pattern as an etching mask. A nitride liner, serving as an oxidation barrier layer, is formed at the sides and bottom of the trench, and is then annealed in a furnace to density the same. In a subsequent etching process, such as that used to remove the etching mask pattern, the densified nitride liner resists being etched. Accordingly, a trench isolation structure having a good profile is produced.
