Abstract: A semiconductor device includes a vertical stack of ring-shaped electrodes that are electrically connected together into a top electrode of a capacitor, on a semiconductor substrate. A bottom electrode of the capacitor is also provided, which extends vertically in a direction orthogonal to a surface of the substrate and through centers of the vertical stack of ring-shaped electrodes. An electrically insulating bottom supporting pattern is provided, which extends between a lowermost one of the ring-shaped electrodes and an intermediate one of the ring-shaped electrodes.

Abstract: Decoupling structures are provided. The decoupling structures may include first conductive patterns, second conductive patterns and a unitary supporting structure that structurally supports the first conductive patterns and the second conductive patterns. The decoupling structures may also include a common electrode disposed between ones of the first conductive patterns and between ones of the second conductive patterns. The first conductive patterns and the common electrode are electrodes of a first capacitor, and the second conductive patterns and the common electrode are electrodes of a second capacitor. The unitary supporting structure may include openings when viewed from a plan perspective. The first conductive patterns and the second conductive patterns are horizontally spaced apart from each other with a separation region therebetween, and none of the openings extend into the separation region.

Abstract: A method and an apparatus for supporting a discontinuous reception (DRX) operation in a Node B in a mobile communication system are provided. The method includes defining a second System Frame Number (SFN) where one cycle of a first SFN corresponds to one bit, transmitting information on the second SFN to a User Equipment (UE), determining a second SFN which is used to transmit a paging signal to the UE, determining a first SFN which is used to transmit the paging signal in the determined second SFN, and transmitting the paging signal to the UE at the determined first SFN.
