| 1 | Effect of organic amine alkali and inorganic alkali on benzotriazole removal during post Cu-CMP cleaning显示文摘Benzotriazole(BTA), an anticorrosion agent of slurry, is the main organic pollutant remaining after CMP of multilayer copper wiring, and also the main removal object of post CMP cleaning. The adsorption of BTA onto the copper could form a dense Cu-BTA film, which makes the copper surface strongly passivated. According to this characteristic, quantitative analysis of BTA residue after cleaning is carried out by contact angle measurement and electrochemical measurement in this paper. A scanning electron microscope(SEM) with EDX was used to observe and analyze the BTA shape and elements. The efficiencies of organic alkali and inorganic alkali on the removal of BTA were studied. The corresponding reaction mechanism was also analyzed. The results show that the adsorption structure of Cu(I)-BTA cannot be destroyed in an alkaline environment with a pH less than 10; the effect of BTA removal by inorganic alkali is worse than that of the organic amine alkali with the coordination structure under the same pH environment; the FA/O Ⅱ chelating agent with the fraction of 200 ppm can effectively remove BTA residue on the surface of copper wafer. | Liu Yang Baimei Tan Yuling Liu Baohong Gao Yilin Liu Chunyu Han Qi Wang Siyu Tian | 2018 | Journal of Semiconductors2018，39，12： | 6 |

| 3 | Deformation transition of intact coal induced by gas injection显示文摘Gas migration in coal bed is a multiple-physical process, of which not only includes gas desorption/diffusion through coal matrix and gas Darcy flow through the cleat system, but also results in deformation of solid coal. Especially for enhanced coal bed methane(ECBM) and CO2 capture and sequestration(CCS), gas injection is mainly controlled by the gas diffusivity in the coal matrix and coal permeability.Although the relevant coal permeability models have been frequently developed, how the dual-porosity system of coal affects gas adsorption/diffusion is still poorly understood. In this paper, a series of experiments were carried out in order to investigate deformation evolution of intact coal subjected to hydrostatic pressure of different gases(including pure H2, N2 and CO2) under isotherm injection. In the testing process, the coal strain and injected gas pressure were measured simultaneously. The results show that the pressure of non-adsorptive helium remained unchanged throughout the isothermal injection process, in which the volumetric strain of the coal shrinked firstly and maintained unchanged at lower isobaric pressure. With the injected pressure increasing, the coal volume underwent a transition from shrinking to recovery(still less than initial volume of the coal). In contrast, N2 injection caused the coal to shrink firstly and then recover with decreasing gas pressure. The recovery volume was larger than the initial volume due to adsorption-induced swelling. For the case of CO2 injection, although the stronger adsorption effect could result in swelling of the solid coal, the presence of higher gas pressure appears to contribute the swelling coal to shrink. These results indicate that the evolution of coal deformation is time dependent throughout the migration of injected gas. From the mechanical characteristics of poroelastical materials, distribution of pore pressure within the coal is to vary with the gas injection,during which the pore pressure in the cleats will rapidly increase, in contrast, the pore pressure in the matrix will hysteretically elevate. Such a difference on changes of pore pressure between the cleats and the matrix will contribute to the shrinkage of the matrix as a result of initially greater effective stress.Besides, both gas-adsorption-induced swelling and decreasing effective stress also control the coal deformation transition. This work gives us an insight into investigation on influence of effective stress on coal-gas interaction. | Wang Chunguang Wang Changsheng Wei Mingyao Gong Bin Tan Yuling | 2014 | International Journal of Mining Science and Technology2014，24，6： | 3 |
| 4 | Optimization of cleaning process parameters to remove abrasive particles in post-Cu CMP cleaning显示文摘The cleaning of copper interconnect chemical mechanical polishing(CMP) is a key process in integrated circuits(ICs) fabrication. Colloidal silica, which is used as the abrasive material in copper CMP slurry, is considered as the main particle contamination. Abrasive particle residuals can cause device failure which need to be removed efficiently. In this paper, a type of CMP cleaner was used for particle removal using a cleaning solution consisting of FA/O Ⅱ chelating agent and FA/O Ⅰ surfactant. By varying the parameters of brush rotation speed, brush gap,and de-ionized water(DIW) flow rate,a series of experiments were performed to determine the best cleaning results. Atomic force microscope(AFM) measurement was used to characterise the surface morphology of the copper surface and the removal of abrasive particles. A scanning electron microscope(SEM) with EDX was used to observe and analyze the particles shape and elements. The optima parameters of CMP cleaner were obtained. Under those conditions, the abrasive silica particles were removed effectively. | Liu Yang Baimei Tan Yuling Liu Baohong Gao Chunyu Han | 2018 | Journal of Semiconductors2018，39，12： | 2 |

| 6 | Flow Characteristics of Crude Oil with High Water Fraction during Non-heating Gathering and Transportation显示文摘In order to ensure the safety of the non-heating gathering and transportation processes for high water fraction crude oil,the effect of temperature,water fraction,and flow rate on the flow characteristics of crude oil with high water fraction was studied in a flow experimental system of the X Oilfield.Four distinct flow patterns were identified by the photographic and local sampling techniques.Especially,three new flow patterns were found to occur below the pour point of crude oil,including EW/O&W stratified flow with gel deposition,EW/O&W intermittent flow with gel deposition,and water single-phase flow with gel deposition.Moreover,two characteristic temperatures,at which the change rate of pressure drop had changed obviously,were found during the change of pressure drop.The characteristic temperature of the first congestion of gel deposition in the pipeline was determined to be the safe temperature for the non-heating gathering and transportation of high water cut crude oil,while the pressure drop reached the peak at this temperature.An empirical formula for the safe temperature was established for oil-water flow with high water fraction/low fluid production rate.The results can serve as a guide for the safe operation of the non-heating gathering and transportation of crude oil in high water fraction oilfields. | LüYuling Tan Hao Li Jiao Yang Donghai Xu Peiyang | 2021 | China Petroleum Processing & Petrochemical Technology2021，23，1： | 1 |

| 8 | VAV2 is required for DNA repair and implicated in cancer radiotherapy resistance显示文摘Radiotherapy remains the mainstay for treatment of various types of human cancer;however,the clinical efficacy is often limited by radioresistance,in which the underlying mechanism is largely unknown.Here,using esophageal squamous cell carcinoma(ESCC)as a model,we demonstrate that guanine nucleotide exchange factor 2(VAV2),which is overexpressed in most human cancers,plays an important role in primary and secondary radioresistance.We have discovered for the first time that VAV2 is required for the Ku70/Ku80 complex formation and participates in non-homologous end joining repair of DNA damages caused by ionizing radiation. | Weiling Liu Chuanwang Miao Shaosen Zhang Yachen Liu Xiangjie Niu Yiyi Xi Wenjia Guo Jiahui Chu Ai Lin Hongjin Liu Xinyu Yang Xinjie Chen Ce Zhong Yuling Ma Yuqian Wang Shihao Zhu Shuning Liu Wen Tan Dongxin Lin Chen Wu | 2021 | Signal Transduction and Targeted Therapy2021，6，9： | 1 |

| 11 | Moving target defense of routing randomization with deep reinforcement learning against eavesdropping attack显示文摘Eavesdropping attacks have become one of the most common attacks on networks because of their easy implementation. Eavesdropping attacks not only lead to transmission data leakage but also develop into other more harmful attacks. Routing randomization is a relevant research direction for moving target defense, which has been proven to be an effective method to resist eavesdropping attacks. To counter eavesdropping attacks, in this study, we analyzed the existing routing randomization methods and found that their security and usability need to be further improved. According to the characteristics of eavesdropping attacks, which are “latent and transferable”, a routing randomization defense method based on deep reinforcement learning is proposed. The proposed method realizes routing randomization on packet-level granularity using programmable switches. To improve the security and quality of service of legitimate services in networks, we use the deep deterministic policy gradient to generate random routing schemes with support from powerful network state awareness. In-band network telemetry provides real-time, accurate, and comprehensive network state awareness for the proposed method. Various experiments show that compared with other typical routing randomization defense methods, the proposed method has obvious advantages in security and usability against eavesdropping attacks. | Xiaoyu Xu Hao Hu Yuling Liu Jinglei Tan Hongqi Zhang Haotian Song | 2022 | Digital Communications and Networks2022，8，3： | 1 |
| 12 | An Electrochemical Cleaning Technique for Removal of Surface Contamination before Texturization of Silicon Solar Cells显示文摘In order to decrease the consumption of reagents and silicon during removal of surface contamination before silicon texturing in solar cell manufacturing industry, a new low-cost surface treatment approach of electrochemical cleaning technique(ECT) is reported. In this technique, a powerful oxidizing electrolyte was obtained from the electrochemical reaction on Boron-doped Diamond(BDD) electrodes, and applied during removal of surface contaminations on silicon wafer surfaces. The slightly polished monocrystalline silicon surfaces after cleaning were compared with the ones of primal silicon wafers. The measurement results show that ECT is quite efficient in removing NaCl and organic contaminants. After cleaning, the contrast test was conducted for the textured silicon wafers with/without pre-treatment(polish) separately. The results show that the size of pyramids on the surface without traditional polishing process is homogeneous and smaller than 4μm, and the average surface reflectance is much lower in the wavelength range from 400nm to 800nm. Therefore, the new technique can save silicon material, and effectively avoid optical losses for improving photoconversion effect of solar cells. | ZHANG Jianxin LIU Yuling TAN Baimei NIU Xinhuan GAO Baohong | 2010 | Semiconductor Photonics and Technology2010，16，1： | 0 |
| 13 | First report of subgenus Phoenicopsis(Czekanowskiales)from Middle Jurassic of Ordos,China and its paleoclimatic implications显示文摘Subgenus Phoenicopsis( Phoenicopsis) assigned to Czekanowskiales is recognized and a new species,Phoenicopsis( Ph.) ordosensis sp. nov. is first reported from the Middle Jurassic Yan'an Formation of the Ordos Basin,alternate based upon the leaf gross morphology and epidermal structures. The new species has linear leavs in bundles of five to six attached on a short shoot,more than 100 mm long by 5-6 mm wide,containing 10-12 parallel veins at upper portion. The leaf is hypostomatic. Epidermal cells are longitudinally arranged with smooth periclinal wall on the upper cuticle. The narrow non-stomatal zones and wide stomatal zones alternate in the lower cuticle. Stomata in four to five irregular spaced rows are longitudinally oriented in each stomatal zone.Guard cells for each are surrounded by four to five subsidiary cells with undeveloped papillae. Anticlinal walls of ordinary epidermal cells are nearly straight and periclinal walls slightly papillate. The new species shallow stomatal pits kept open and surrounded by unevenly undeveloped bulges. These characters are consistent with those of growth in a humid,rather than an arid climate. The presence of subgenus Phoenicopsis and other taxa of Czekanowskiales in the coal-bearing Yan'an Formation supports the view that the climate in the Ordos Basin was humid and warm with seasonal changes during the Middle Jurassic. | LI Tao LI Yunfeng NA Yuling HUANG Wei TAN Xiao SUN Chunlin | 2015 | Global Geology2015，18，3： | 0 |
| 14 | Multi-Agent System for Electric Vehicle Charging Scheduling in Parking Lots显示文摘As the number of electric vehicles(EVs)increases,massive numbers of EVs have started to gather in commercial parking lots to charge and discharge,which may significantly impact the operation of the grid.There may also be a deviation in the departure time of charged and discharged EVs in commercial parking lots.This deviation can lead to insufficient battery energy when the EVs leave the parking lot.This study uses the simulation software AnyLogic to build a commercial parking lot multi-agent simulation model,and the agent-based model can fully reflect the autonomy of individual EVs.Based on this simulation model,we propose an EV scheduling algorithm.The algorithm contains two main agents.The first is the power distribution center agent(PDCA),which is used to coordinate the energy output of photovoltaic(PV),energy storage system(ESS),and distribution station(DS)to solve the problem of grid overload.The second is the scheduling center agent(SCA),which is used to solve the insufficient battery energy problem due to EVs’random departures.The SCA includes two stages.In the first stage,a priority scheduling algorithm is proposed to emphasize the fairness of EV charging.In the second stage,a genetic algorithm is used to accurately determine the time interval between charging and discharging to ensure the maximum benefit of EV owner.Finally,simulation experiments are conducted in AnyLogic,and the results demonstrate the superiority of the algorithm over the classical algorithm. | Mao Tan Zhonglin Zhang Yuling Ren Irampaye Richard Yuzhou Zhang | 2023 | Complex System Modeling and Simulation2023，3，2： | 0 |

| 16 | A new model for thermal conductivity of“continuous matrix/dispersed and separated 3D-particles”type composite materials and its application to WC-M(M=Co,Ag)systems显示文摘In the present work a new thermal conductivity model is developed for two-phase composite materials,which are consisted of a continuous matrix and dispersed 3 D-particles separated from each other by the matrix as a function of grain size and volume ratio of the dispersed particles at different temperatures.The model is applied to reproduce experimental thermal conductivity values of cemented carbide systems WC-Co and WC-Ag.Good agreement was found between measured thermal conductivity data originating from both this work and recent literature and the calculated ones only using semi-empirical parameters for the interfacial thermal resistance(ITR)values at WC/Co,WC/Ag and WC/WC interfaces as a function of temperature.Additionally,the temperature and grain size dependence of the thermal conductivity for WC is established for the first time.The model works well for the case when the matrix(Ag)has a higher thermal conductivity compared to that of the WC particles and also for the case when the matrix(Co)has a lower thermal conductivity compared to that of the WC particles.The new model forms a physically sound basis for further development/materials design of cemented carbides and particlereinforced composite materials. | Shiyi Wen Yong Du Jing Tan Yuling Liu Peng Zhou Jianzhan Long George Kaptay | 2022 | Journal of Materials Science & Technology2022，，2： | 0 |
