With the continued shrinking of the critical dimensions (CDs) of wafer patterning, the requirements for modeling precision in optical proximity correction (OPC) increase accordingly. This requirement extends beyond CD controlling accuracy to include pattern alignment accuracy because misalignment can lead to considerable overlay and metal-via coverage issues at advanced nodes, affecting process window and yield. This paper proposes an efficient OPC modeling approach that prioritizes pattern-shift-related elements to tackle the issue accurately. Our method integrates careful measurement selection, the implementation of pattern-shift-aware structures in design, and the manipulation of the cost function during model tuning to establish a robust model. Confirmatory experiments are performed on a via layer fabricated using a negative tone development. Results demonstrate that pattern shifts can be constrained within a range of +/- 1 nm, remarkably better than the original range of +/- 3 nm. Furthermore, simulations reveal notable differences between post OPC and original masks when considering pattern shifts at locations sensitive to this phenomenon. Experimental validation confirms the accuracy of the proposed modeling approach, and a firm consistency is observed between the simulation results and experimental data obtained from actual design structures.

满族作家马加很早就投身到救国救民的革命事业中。在马加现代时期的创作中,抗战书写是其文学创作的重心。纵观马加的抗战书写,中华民族观对其产生了重要影响。从总体上看,反帝抗战是马加抗战书写的重心,这揭示出马加在民族国家危难时具有的责任感和义务感;在抗战书写中,阶级特性是其中的显著特色之一,这是马加接受中华民族观的重要视域;同时,抗战书写还与现代乡村革命密切结合,由此显示出马加对中华民族新进程中乡村变革作用的深切体悟。

本文构建了国家海洋公园建设和海洋经济高质量发展评价指标体系,采用熵值法确定各指标权重,基于耦合协调模型研究沿海九省(区)(不含港澳台地区)国家海洋公园建设与海洋经济高质量发展耦合协调关系。结果显示:样本期内,沿海九省(区)国家海洋公园建设和海洋经济高质量发展综合评价得分具有非均衡性和非平稳性。耦合协调度结果表明,各省(区)国家海洋公园建设与海洋经济高质量发展耦合协调度存在明显的分界,两系统耦合阶段多处于拮抗和磨合阶段,且主要表现为低度耦合和中度耦合协调水平。从灰色关联分析结果可知,各指标中与沿海九省(区)两系统耦合协调度关联最高的指标均为反映海洋经济高质量发展的指标。本文通过分析沿海九省(区)国家海洋公园建设与海洋经济高质量发展耦合协调情况,为促进国家海洋公园建设与海洋经济高质量发展的良性互动提供参考。

在新旧动能转化及创新驱动发展战略的背景下,聚焦于以制造业和生产性服务业表示的异质性企业协同集聚,探索其对城市创新活力发挥的能动作用具有重要的现实意义。基于2005—2021年城市和企业两个层级的面板数据,使用双固定效应模型、中介效应模型和空间杜宾模型进行系统性分析,发现异质性企业协同集聚对城市创新活力产生显著的正向影响,且表现出明显的区域、城市行政级别、资源禀赋和细分行业的异质性。异质性企业协同集聚产生的空间溢出效应,随地理距离阈值增加而呈现出以900km为界线先促进后抑制的特征,且存在1300km处的衰减边界。机制表明,上游供应商多元化、下游客户多元化和供应链配置多元化是异质性企业协同集聚促使城市创新活力上升的渠道。市场潜力和制度环境作为互补性条件,发挥“放大镜”作用,能增强异质性企业协同集聚的城市创新活力效应。研究结论为跨行业企业协同集聚、深化产业分工任务和驱动城市创新活力上升提供有益见解。

理论分析高阶激光模式在激光稳频系统中的热噪声,并给出模式类型和阶数、激光功率、分析频率等参数对热噪声、散粒噪声以及总噪声的影响。给出激光稳频系统的一般噪声模型,将其应用于高阶模式的稳频系统并分析噪声传递过程。理论计算高阶模稳频系统中参考腔的热噪声,对比高阶厄米-高斯和拉盖尔-高斯模式的基底热噪声,在同一阶数下,拉盖尔模式比厄米模式的热噪声更低。LG_(10,0)模式在1 Hz处产生的热噪声相比于基模热噪声降低了16%。综合散粒噪声的影响,得到LG_(p,0)模式在0≤p≤25范围内参考腔的最低总噪声在1 Hz处可以达到0.022 Hz/Hz^(1/2),相比于基模总噪声降低了23%。使用该方式可以很好地控制激光器频率噪声以减少对引力波探测的影响。
