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.

摘要： An isolation region is formed on a substrate by forming spaced apart mesas on the substrate. A first insulation region is then formed on the substrate and second insulation regions are formed on the mesas, the first insulation region being disposed between and spaced apart from a respective one of the mesas, a respective one of the second insulation regions capping a respective one of the mesas. Preferably, the first and second insulation regions are formed by forming sidewall spacers adjacent sidewall portions of the mesas and oxidizing portions of the mesas opposite the substrate and a portion of the substrate disposed between the sidewall spacers. Spaced apart trenches are formed in the substrate on opposite sides of the first insulation region, a respective one of the trenches being disposed between the first insulation region and a respective one of the mesas, preferably by removing the sidewall spacers and underlying portions of the substrate. An insulating layer is formed on the substrate, filling the trenches and covering the first insulation region, and the substrate is planarized to remove portions of the insulating layer and the second insulation regions and thereby expose underlying portions of the mesas and leave a third insulation region spanning the trenches.

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.
