    • Techniques are disclosed for enhancing the dielectric breakdown performance of integrated circuit (IC) interconnects. The disclosed techniques can be used to selectively etch the dielectric layer of an IC to form a recess, for example, between a given pair of adjacent/neighboring interconnects (e.g., metal lines). Thereafter, a layer of dielectric material of higher dielectric breakdown field (Ec) than the surrounding/underlying dielectric material (or other suitable insulator, as will be apparent in light of this disclosure) may be deposited/grown so as to substantially conform to the topology provided by the adjacent/neighboring interconnects and etched recess. In some cases, this dielectric layer may help to prevent or otherwise reduce: (1) dielectric breakdown between the adjacent/neighboring interconnects by locally increasing the dielectric breakdown voltage (VBD); and/or (2) diffusion of the interconnect fill metal into the surrounding/underlying dielectric material. In some instances, such a layer may serve as an etch stop.
    • 公开了用于增强集成电路(IC)互连的介质击穿性能的技术。 所公开的技术可以用于选择性地蚀刻IC的电介质层,以形成例如在给定的一对相邻/相邻互连(例如,金属线)之间的凹部。 此后,可以沉积/生长比围绕/下面的电介质材料(或其他合适的绝缘体)更高的电介质击穿电场(Ec)的电介质材料层,以便基本上符合 拓扑由相邻/相邻互连和蚀刻凹槽提供。 在一些情况下,该介电层可以有助于防止或以其它方式减少:(1)通过局部增加介电击穿电压(VBD)来在相邻/相邻互连之间的介质击穿; 和/或(2)互连填充金属扩散到周围/下面的介电材料中。 在一些情况下,这样的层可以用作蚀刻停止。

    • Techniques for performing traffic classification for uplink and bi-directional traffic streams are described. A station receives packets for transmission on the uplink to an access point. The station identifies packets for each uplink traffic stream and packets for each bi-directional traffic stream based on at least one classification parameter for each traffic stream. The station sends packets for each traffic stream in accordance with at least one QoS parameter for the traffic stream. The access point receives packets for transmission on the downlink to at least one station. The access point identifies packets for each downlink traffic stream and packets for each bi-directional traffic stream based on at least one classification parameter for each traffic stream. The access point sends packets for each traffic stream in accordance with at least one QoS parameter for the traffic stream.

    • A ceiling-mount omnidirectional antenna for indoor distribution system of mobile communication network and a method for manufacturing the same are provided. The antenna includes: a monopole consisting of a cone part and a columnar part; a reflecting plate consisting of a cone part and a platform part; and a feed connector. The monopole and the reflecting plate are arranged in such that the tips of cone parts are opposite to each other. The signal is fed into the antenna through the feed connector and radiated outward by the monopole and the reflecting plate. In high frequency band, the maximal gain appears at about 70°, so that the signal power focuses at radiating angles of 60°˜85°. Comparing to the existing antenna, the gain of the antenna increases 4.22 dB at a radiating angle of 85° and decreases 10 dB at a radiating angle of 30°. So, the maximal permissible value of antenna aperture power of mobile communication signal in high frequency band, such as 3G, is increased; and the field strength of signal covering the edge is increased. The antenna can increase the covering range of a single antenna, increase the signal quality, and cover 2G and 3G networks in the same time so as to reduce the difficulty and the cost for building and reconstructing an indoor distribution system in 3G.
    • 提供了一种用于移动通信网络室内分配系统的天花板安装全向天线及其制造方法。 天线包括:由锥形部分和柱状部分组成的单极子; 由锥体部分和平台部分组成的反射板; 和馈电连接器。 单极子和反射板被布置成使得锥形部分的尖端彼此相对。 信号通过馈电连接器馈入天线,并由单极子和反射板向外辐射。 在高频段,最大增益出现在70°左右,信号功率在60°〜85°的辐射角度下聚焦。 与现有天线相比,天线的增益在85°的辐射角下增加了4.22dB,在30°的辐射角下降低了10dB。 因此,3G等高频移动通信信号的天线孔径功率的最大允许值增加; 并且覆盖边缘的信号的场强增加。 天线可以增加单个天线的覆盖范围,提高信号质量,同时覆盖2G和3G网络,降低3G中室内分布系统建设和重建的难度和成本。
