    Abstract: A semiconductor device has a silicon substrate, in which an active region is formed between two device isolation films and a gate is formed on the surface of the active region. The silicon substrate has a laterally etched portion in the active region below the surface of the active region on the side near the device isolation film. An insulating film is formed on the laterally etched portion of the silicon substrate. A conductive electrode is formed on the insulating film, through which an external voltage is applied to adjust a threshold voltage. The device isolation film is formed on the conductive electrode. None or some pockets of vacant cavity is present between the device isolation film and the conductive electrode.

  • Publication number: 20070117201
    Abstract: The present invention relates to a plastic chip for PCR, having polymer valves, and more particularly to a plastic chip for PCR, having polymer valves, which can perform the temperature cycling of a small amount (nanoliter) of a sample in a microchamber at a constant temperature sensitively to temperature gradient. The inventive plastic PCR chip can perform a PCR even with a small amount of a sample through a reduction in the size of a PCR chamber included in the chip, compared to the prior PCR chip. Also, as the surface area of the PCR chamber is increased, the time taken for heating and cooling can be decreased, thus reducing reaction time. In addition, the inventive plastic PCR chip is mounted with one or more PCR chambers, so that it can amplify various genes at the same time.

  • Publication number: 20050245073
    Abstract: In a method for forming a contact plug of a semiconductor device, epitaxial silicon is formed as contact material using a solid-phase epitaxy method. The method can obtain reduced contact resistance and improved refresh characteristics, compared with prior arts using polysilicon as contact material. Also, the method uses an SPE method, not a conventional SEG method, to form epitaxial silicon so that it can substantially reduce thermal budget through low-temperature processes. The method can also use conventional polysilicon deposition process without modification to form epitaxial silicon with ease and productivity.

  • Publication number: 20050200392
    Abstract: Output buffer slew rate variation over variations in load capacitance is minimized by dividing output voltage transitions into distinct time and output current segments. During the first time segment, the first drive stage with the smallest current is employed. After subsequent delays, additional drive stages are employed and the load current is sequentially increased. Each drive stage employs a specifically sized feedback device which, depending upon its dimensions will provide either parasitic capacitance to slow transitions or positive feedback to speed up transitions. The first stages are sized to incorporate parasitic capacitance, resulting in little change in the settling time of small capacitance loads over prior art output buffers. Latter stages use positive feedback to quicken the transition time which dramatically improves the settling time for larger load capacitances over prior art output buffers.

  • Publication number: 20050164512
    Abstract: Disclosed is a method of manufacturing a semiconductor device. The method comprises the steps of: preparing a silicon substrate having a predetermined lower structure including a gate and a bonding area; forming an interlayer dielectric film on the top side of the substrate; forming a photosensitive film pattern, which exposes an area for providing contact, on the interlayer dielectric film; forming a contact hole exposing a bonding area of the substrate by etching the exposed part of the interlayer dielectric film; removing the photosensitive film pattern; performing a dry cleaning on the exposed bonding area of the substrate so that CF based polymer formed in the etching step is removed; and performing a nitrogen-hydrogen plasma processing on the surface of the exposed bonding area of the substrate so that oxygen polymer and remaining CF-based polymer are removed. Therefore, since hydrogen plasma processing is performed after contact etching, ohmic contact characteristics can be secured.
