摘要： A recessed gate structure in a semiconductor device includes a gate electrode partially buried in a substrate, a blocking member formed in the buried portion of the gate electrode, and a gate insulation layer formed between the gate electrode and the substrate. The blocking member may effectively prevent a void or a seam in the buried portion of the gate electrode from contacting the gate insulation layer adjacent to a channel region in subsequent manufacturing processes. Thus, the semiconductor device may have a regular threshold voltage and a leakage current passing through the void or the seam may efficiently decrease.

摘要： A coupling capacitor and a semiconductor memory device using the same are provided. In an embodiment, each memory cell of the semiconductor memory device includes a coupling capacitor so that a storage capacitor can store at least 2 bits of data. The coupling capacitor has a capacitance having a predetermined ratio with respect to the capacitance of the storage capacitor. For this, the coupling capacitor is formed by substantially the same fabrication process as the storage capacitor. The predetermined ratio is obtained by choosing an appropriate number of individual capacitors, each with the same capacitance of the storage capacitor, to comprise the coupling capacitor. Also, the coupling capacitor is disposed on an interlayer insulating layer that buries a bit line in a cell region and a sense amplifier in a sense amplifier region.

摘要： According to some embodiments of the invention, a method of forming a transistor includes forming a device isolation layer in a semiconductor substrate. The device isolation layer is formed to define at least one active region. A channel region is formed in a predetermined portion of the active region of the semiconductor substrate. Two channel portion holes are formed to extend downward from a main surface of the semiconductor substrate to be in contact with the channel region. Gate patterns fill the channel portion holes and cross the active region. The resulting transistor is capable of ensuring a constant threshold voltage without being affected by an alignment state of the channel portion hole and the gate pattern.

摘要： A method of and system for driving a plasma display panel (PDP), which is designed to increase the amount of data processed in unit time. The method includes the steps of dividing row electrodes into at least two groups, splitting the field, and applying driving pulses to each split field with a phase difference. Also, the present invention uses a lower bit preceding scanning method where the bits of a digital picture signal are aggregated by bits of a kind from the most significant bit to the least significant bit and divided into a plurality of pairs of upper and lower bits as (lower bit, upper bit), the lower bit in each pair of bits being successively scanned, followed by a scanning of the upper bit in each pair of bits. Thus, the efficiency of the AC PDP is enhanced with the reduction in the time needed to construct the field, and readily driving a field even when the amount of data to be scanned is increased.
