    摘要: A CMOS semiconductor device and a method of manufacturing the same in which the gate induced drain leakage (GIDL) effect is reduced. In the semiconductor device of this invention, high concentration source/drain regions of a PMOS transistor are formed away from the gate pattern sidewall spacers. This is accomplished by using as an implant mask a dielectric film formed on an entire surface of a semiconductor substrate, where the semiconductor substrate includes a PMOS transistor region in an n-well, a low concentration source/drain regions of a PMOS transistor formed by using a gate pattern as an implant mask, the PMOS transistor gate pattern sidewall spacers, and an NMOS transistor region in a p-well with the NMOS transistor having both a low concentration and a high concentration source/drain regions.

    摘要: A method of forming an isolation film forms a spacer for connecting the edge of an active region to the isolation film. The spacer is on the upper sidewall of a trench and smoothes the transition or step between the level of the isolation film and the level of the active region. Accordingly, a gate oxide film of a uniform thickness can be formed on the entire active region in a subsequent process, thus preventing degradation of the characteristics of the gate oxide film. The spacer can be formed using a sidewall spacer on the hard mask used for forming the trench. The sidewall spacer protects part of the isolation formed in the trench, and etching after removal of the sidewall spacer can round the protected portion to create the spacer. Furthermore, to dispel stresses and defects in the isolation film, annealing for densification of the isolation film can be performed at a high temperature such as about 1150° C. because the spacer mitigates the effects of shrinking or sagging of the isolation film.

    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.
