    • Disclosed is an apparatus and method for an MBS service in a BWA system. An apparatus of a base station includes a time controller, a CAC processor, and a buffer controller. The time controller manages a broadcast start time and a broadcast end time and generates a broadcast start message at a predetermined time before the actual broadcast start time. Upon receipt of the generated broadcast start message from the time controller, the CAC processor calculates a capacity decrease due to broadcast service and subtracts the capacity decrease from the current available capacity to update the available capacity. Upon receipt of the generated broadcast start message from the time controller, the buffer controller controls the buffer occupation of unicast traffic in order to provide the buffer space required for a broadcast service.

    • Disclosed herein are a semiconductor device and a method of manufacturing the same that increases the reliability of these devices as size design limitations decrease. Generally, a first insulating film, and wiring, including conductive film patterns and second insulating film patterns are formed on a substrate. Third insulating film patterns including a silicon-oxide-based material are formed on sidewalls of the wiring, and contact patterns and spacers on the sidewalls thereof for defining contact hole regions are formed on the wiring. The contact holes contact surfaces of the third insulating film patterns and pass through the first insulating film. Thus, the thickness of a second insulating film pattern used in the wiring can be minimized, thereby increasing a gap-fill margin between the wiring. A parasitic capacitance between the wiring can be reduced because silicon oxide spacers with a low dielectric constant are formed on sidewalls of the wiring.
    • 本文公开了一种半导体器件及其制造方法,其随着尺寸设计限制的降低而增加这些器件的可靠性。 通常,在基板上形成包括导电膜图案和第二绝缘膜图案的第一绝缘膜和布线。 在布线的侧壁上形成包括基于氧化硅的材料的第三绝缘膜图案,并且在布线上形成用于限定接触孔区域的侧壁上的接触图形和间隔物。 接触孔接触第三绝缘膜图案的表面并穿过第一绝缘膜。 因此,可以使布线中使用的第二绝缘膜图案的厚度最小化,从而增加布线之间的间隙填充余量。 由于在布线的侧壁上形成具有低介电常数的氧化硅间隔物,所以布线之间的寄生电容可以减小。
