    摘要: Active areas of integrated circuits can be formed by implanting first ions into a first active area of a substrate adjacent to an isolation structure in the substrate and between a source and a drain region of the integrated circuit to provide a first concentration of ions in the first active area. Second ions are implanted into the first active area and a second active area of the substrate adjacent to the first active area and spaced-apart from the isolation structure on the substrate to provide a second concentration of ions in the second active area and a third concentration of ions in the first active area that is greater than the first and second concentrations. As a result, the level of ion concentration can be higher at the edge of an active channel region than at the center of the channel. The increased concentration of ions in the active area adjacent to the side wall of the trench may reduce a current between the source and drain regions of the transistor when voltage that is less than a threshold voltage of the transistor is applied to the gate electrode of the transistor. Thus, a reduction in the threshold voltage of the transistor can be inhibited. Integrated circuit transistors are also disclosed.

    摘要: A ferroelectric capacitor with a ferroelectric film having a relatively larger amount of titanium constituent than zirconate constituent improves ferroelectric characteristics. The method for fabricating the ferroelectric capacitor includes the step of performing a heat treatment in an oxygen atmosphere after forming a contact opening in an insulating layer which covers an already formed ferroelectric capacitor. This heat treatment in an oxygen atmosphere can minimize undesirable side effects resulting from a platinum electrode oxidizing the ferroelectric film components.

    摘要: A method of forming a semiconductor device wherein a dummy cell region is defined at a periphery of a cell array region that includes a ferroelectric capacitor. A dummy capacitor is formed simultaneously at the dummy cell region when a ferroelectric capacitor is formed at the cell array region. Accordingly, plasma etching damage and electrical charge generation are concentrated on the dummy capacitor, thereby reducing plasma etching damage and electrical charge generation at the ferroelectric capacitor of the cell array region.

    摘要: An etch-stop layer is selectively provided between layers of a multiple-layered circuit so as to allow for outgassing of impurities during subsequent fabrication processes. The etch-stop layer is formed over an underlying stud so as to serve as an alignment target during formation of an overlying stud formed in an upper layer to be coupled to the underlying stud. In this manner multiple-layered circuits, for example memory devices, can be fabricated in relatively dense configurations.

    摘要: Narrow-channel effect free DRAM cell transistor structure for submicron isolation pitch DRAMs having lowed-doped substrate and active width-independent threshold voltage by employing conductive shield in the shallow trench isolation(STI). The resulting cell transistor structure is highly immune to parasitic E-field penetration from the gate and neighbouring storage node junctions via STI and will be very appropriate for Gbit scale DRAM technology. The conductive shield is biased with the negative voltage in order to minimize the sidewall depletion in the substrate.

    摘要: A semiconductor device includes a semiconductor substrate having an active region and an isolation region. A gate structure is provided on the semiconductor device. First and second impurity regions are provided in the substrate on both sides of the gate structure. A pad electrode is provided to contact the first impurity region. Because the pad electrode is provided on the first impurity region of the semiconductor device, the contact plug does not directly contact the active region. Accordingly, failures caused by damage to the active region may be prevented.
