    摘要: A method for fabricating a capacitor of a semiconductor device, and a capacitor made in accordance with the method, wherein the method includes forming a plate electrode polysilicon layer on a semiconductor substrate having a cell array region and a core/peripheral circuit region. The plate electrode polysilicon layer in the cell array region is patterned to form an opening, wherein the inner wall of the opening is used as a plate electrode. After forming a dielectric layer in the opening, a storage node is formed as a spacer on the dielectric layer on the inner wall of the opening. The plate electrode polysilicon layer in the core/peripheral circuit region remains to provide the same height between the cell array region where the cell capacitor is formed and the core/peripheral circuit region.

    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.

As a result, it is possible to greatly secure the alignment of a buried contact electrically connected to the pad.

    摘要: Ferroelectric memory devices include a plate line, a bit line, a ferroelectric memory cell containing a first access transistor and a first ferroelectric capacitor electrically connected in series between the bit line and the plate line, and a word line electrically connected to a gate electrode of the first access transistor. A row decoder and a preferred plate line pulse generator are also provided to generate a write voltage of first magnitude (e.g., Vcc) on the plate line during a write time interval and a read voltage of a second magnitude (e.g., Vcc+&agr;), greater than the first magnitude, on the plate line during a read time interval. These different magnitudes of the write and read voltage for the plate line are generated in response to a control signal (CP), so that during a read operation, the magnitude of the change in voltage across the ferroelectric capacitor will be sufficient to enable a complete charge transfer of 2QR when the ferroelectric memory cell is storing a data 1 value. The plate line pulse generator may comprise a pulse generator, a voltage boosting circuit having an input electrically coupled to an output of the pulse generator and a switch circuit to electrically couple an output of the pulse generator to an output of the plate line pulse generator when the control signal is in a first logic state (during a write operation) and electrically couple an output of the voltage boosting circuit to the output of the plate line pulse generator when the control signal is in a second logic state (during a read operation).

    摘要: A method for fabricating a semiconductor device with different gate oxide layers is provided. In this method, oxidation is controlled in accordance with the active area dimension so that the oxide grows more thinly at a wider active width in a peripheral region, and grows more thickly at a narrower active width in a cell array region. In this method, a gate pattern is formed over a semiconductor substrate having different active areas. Gate spacer are formed and an active-dimension-dependant oxidation process is then performed to grow oxide layers of different thicknesses in the cell array region and the peripheral region.
