    • An optical lithography method is disclosed that uses double exposure of a reusable a chromeless alternating phase-shifting template mask and a binary trim mask to fabricate regularly-placed rectangular contacts in standard cells of application-specific integrated circuits (ASICs). A first exposure of the reusable chromeless alternating phase-shifting template ask forms periodic dark lines on a wafer and a second exposure of binary tri mask remove the unwanted part of the dark lines and the small cuts of the dark lines left form the rectangular-placed contacts. All contacts are placed regularly in one direction while randomly in the perpendicular direction. The method of the invention can be used in the fabrication of standard cells in application-specific integrated circuits (ASICs) to decrease circuit area an improve circuit performance.
    • 公开了一种光学光刻方法,其使用可重复使用的无铬交替相移模板掩模和二进制修整掩模的双重曝光来制造专用集成电路(ASIC)的标准单元中的规则放置的矩形触点。 可重复使用的无铬交替移相模板问的第一次曝光在晶圆上形成周期性的黑线,并且二元三掩模的第二次曝光去除不需要的部分黑线和剩余的黑线的小切割形成矩形放置 联系人。 所有触点均按照一个方向定期放置,同时在垂直方向随机放置。 本发明的方法可用于在专用集成电路(ASIC)中制造标准单元以减小电路面积和提高电路性能。

    • A method and system for allocating an uplink control region (201) to both HARQ ACKCH and CQICH in order to maximize uplink bandwidth for data transfer in a communication network. A control region scheduling (CRS) utility (110) assigns (402) a higher priority to HARQ ACKCH relative to CQICH. When both HARQ ACKCH and CQICH are to be allocated for a subscriber (101-103) in the same region (201) in the same frame (200), HARQ ACKCH is allocated in the region while CQICH is rejected (406). As the substitute to the rejected CQICH, the CRS utility may use current uplink channel quality information in combination with the corresponding HARQ ACK transmission to estimate (407) a downlink channel quality for the subscriber. Upon receiving the HARQ ACK information, the CRS utility updates (409) the subscriber(s) uplink channel quality information. The CRS utility also may activate or de-activate the uplink control region sharing.
    • 一种用于向HARQ ACKCH和CQICH两者分配上行链路控制区域(201)以便最大化通信网络中的数据传输的上行链路带宽的方法和系统。 控制区域调度(CRS)实用程序(110)相对于CQICH向HARQ ACKCH分配(402)较高优先级。 当同一帧(200)中相同区域(201)中的用户(101-103)都要分配HARQ ACKCH和CQICH两者时,HARQQCH被分配在该区域,而CQICH被拒绝(406)。 作为拒绝的CQICH的替代品,CRS实用程序可以使用当前的上行链路信道质量信息与相应的HARQ ACK传输相结合来估计(407)用户的下行链路信道质量。 在接收到HARQ ACK信息时,CRS实用程序更新(409)订户上行链路信道质量信息。 CRS实用程序还可以激活或去激活上行链路控制区域共享。
