    摘要: Methods of forming a semiconductor device include forming a trench mask pattern on a semiconductor substrate having active regions and device isolation regions. A thermal oxidation process is performed using the trench mask pattern as a diffusion mask to form a thermal oxide layer defining a convex upper surface of the active regions. The thermal oxide layer and the semiconductor substrate are etched using the trench mask pattern as an etch mask to form trenches defining convex upper surfaces of the active regions. The trench mask pattern is removed to expose the convex upper surfaces of the active regions. Gate patterns are formed extending over the active regions.

    摘要: A buried bit line DRAM cell and a manufacturing method thereof are provided. The buried bit line DRAM cell has a buried bit line formed into a trench which isolates devices, the buried bit line being isolated from a semiconductor substrate, a gate formed to be orthogonal to the bit line on the substrate, a first insulating layer formed to insulate the gate, a source and a drain of a transistor formed on the substrate at both sides of the gate, a self-aligned bit line contact formed between the first insulating layers for making contact between the drain and the buried bit line, and a self-aligned buried contact formed between the first insulating layers for making contact between the source and a storage electrode. According to the above structure, misalignment between the gate and the bit line and the excessive exposure to thermal processing which are inherent in conventional Buried Bit Line cells can be avoided and the design rule margin can be improved.

    摘要: Memories, pre-charge circuits, and methods for pre-charging memory are described. One such method includes providing a voltage to a data line and adjusting the voltage provided to the data line based at least in part on a voltage difference between a target voltage and a voltage of the data line being pre-charged. An example pre-charge circuit includes a voltage generator configured to generate an output voltage having a magnitude based at least in part on a reference voltage and a feedback signal, first and second drivers, and a voltage detector. The voltage detector is configured to determine a voltage difference between the reference voltage and a sample voltage of a data line coupled to the second driver and generate the feedback signal based at least in part on the difference.

    摘要: In a method of forming a semiconductor device, a feature layer is provided on a substrate and a mask layer is provided on the feature layer. A portion of the mask layer is removed in a first region of the semiconductor device where fine features of the feature layer are to be located, the mask layer remaining in a second region of the semiconductor device where broad features of the feature layer are to be located. A mold mask pattern is provided on the feature layer in the first region and on the mask layer in the second region. A spacer layer is provided on the mold mask pattern in the first region and in the second region. An etching process is performed to etch the spacer layer so that spacers remain at sidewalls of pattern features of the mold mask pattern, and to etch the mask layer in the second region to provide mask layer patterns in the second region. The feature layer is etched using the mask layer patterns as an etch mask in the second region and using the spacers as an etch mask in the first region to provide a feature layer pattern having fine features in the first region and broad features in the second region.
