    摘要: A semiconductor device is manufactured by forming trenches in a substrate and selectively performing Plasma Ion Immersion Implantation and Deposition (PIIID) on a subset of the trenches in the substrate. The PIIID may be performed on only a portion of a surface of at least one of the trenches in the substrate. Semiconductor devices can include a semiconductor substrate having first, second and third trenches therein, and an oxide liner layer that fully lines the first trenches, that does not line the second trenches and that partially lines the third trenches.

    摘要: Methods of manufacturing a semiconductor device, which can reduce hot electron induced punchthrough (HEIP) and/or improve the operating characteristics of the device include selectively forming an oxynitride layer in a device isolation layer according to the characteristics of transistors isolated by the device isolation layer. The methods include forming first trenches and second trenches on a substrate, forming an oxide layer on the surfaces of the first trenches and the second trenches, selectively forming an oxynitride layer on the second trenches by using plasma ion immersion implantation (PIII), and forming a buried insulating layer in the first trenches and the second trenches. The buried insulating layer may be planarized to form a first device isolation layer in the first trenches and a second device isolation layer in the second trenches.

    摘要: Trench isolation methods for integrated circuits may reduce irregularities in the formation of an isolation layer through use of a high selectivity chemical-mechanical polishing (CMP) operation. In particular, a substrate surface is etched to form a trench. An insulation layer is then formed on the substrate surface and in the trench. The insulation layer is chemical-mechanical polished using a slurry that includes a CeO2 group abrasive to form an isolation layer in the trench. The CMP selectivity ratio of a slurry that includes a CeO2 group abrasive may be sufficient to allow the substrate surface to be used as a CMP stop. As a result, a more consistent level of polishing may be maintained over the substrate surface, which may result in a more uniform thickness in the isolation layer.
