| 1 | Challenges of 22 nm and beyond CMOS technology显示文摘It is predicted that CMOS technology will probably enter into 22 nm node around 2012. Scaling of CMOS logic technology from 32 to 22 nm node meets more critical issues and needs some significant changes of the technology, as well as integration of the advanced processes. This paper will review the key processing technologies which can be potentially integrated into 22 nm and beyond technology nodes, including double patterning technology with high NA water immersion lithography and EUV lithography, new device architectures, high K/metal gate (HK/MG) stack and integration technology, mobility enhancement technologies, source/drain engineering and advanced copper interconnect technology with ultra-low-k process. | HUANG Ru WU HanMing KANG JinFeng XIAO DeYuan SHI XueLong AN Xia TIAN Yu WANG RunSheng ZHANG LiangLiang ZHANG Xing WANG YangYuan | 2009 | Science in China(Series F)2009，52，9： | 8 |
| 2 | Modulate the superficial structure of La_(2)Ce_(2)O_(7) catalyst with anchoring CuO_(x) species for the selective catalytic oxidation of NH_(3)显示文摘Air contamination caused by the ammonia slip phenomenon has gradually captured the researcher’s extensive attention.An effective strategy for controlling fugitive NH_(2)is critical to improving the air quality and living environment.In the present work,CuO_(x)/La_(2)Ce_(2)O_(7)composite as a potential candidate catalyst is synthesized through the electrostatic adsorption method for the selective catalytic oxidation(SCO_(2))of NH_(2)to N.The 5%Cu Ox/La_(2)Ce_(2)O_(7)exhibits the best catalytic activity(T=243℃)and ammonia conversion efficiency.The improvement of performance is mainly attributed to the superficial connection of[Ce-O-Cu],which enhances the capturing ability of ammonia molecule and accelerates the dissociating efficiency of N–H bonding for Nevolution,simultaneously.This work provides a facile method to synthesis pyrochlore-like composite catalyst of NH_(2)-SCO_(2) for solving the problem of ammonia slip pollution in the future. | Xiangchen Kong Zhenguo Li Yuankai Shao Xiaoning Ren Kaixiang Li Hanming Wu Congjie Lv Cheng Lv Shengli Zhu | 2022 | Journal of Materials Science & Technology2022，，16： | 1 |

| 4 | Parameter Estimation of a Spherical Top Inductively Coupled Plasma Source with Global Model显示文摘Using spatially averaged global model,we succeed in obtaining some plasma parameters for a low pressure inductively coupled plasma source of our laboratory.As far as the global balance is concerned,the models can give reasonable results of the parameters,such as the global electron temperature and the ion impacting energy,etc.It is found that the ion flow is hardly affected by the neutral gas pressure.Finally,the magnetic effects are calculated by means of the method.The magnetic field can play an important role to increase plasma density and ion current. | WU Hanming LI Ming CHEN Yunming WU Chengkang | 1995 | Chinese Physics Letters1995，12，5： | 0 |

| 6 | A 65-nm 1-Gb NOR floating-gate flash memory with less than 50-ns access time显示文摘This paper presents a 65-nm 1-Gb NOR-type floating-gate flash memory,in which the cell device and chip circuit are developed and optimized.In order to solve the speed problem of giga-level NOR flash in the deep submicron process,the models of long bit-line and word-line are first given,by which the capacitive and resistive loads could be estimated.Based on that,the read path and key modules are optimized to enhance the chip access property and reliability.With the measurement results,the flash memory cell presents good endurance and retention properties,and the macro is operated with 1-ls/byte program speed and less than 50-ns read time under 3.3 V supply. | Yu Wang Zongliang Huo Huamin Cao Ting Li Jing Liu Liyang Pan Xing Zhang Yun Yang Shenfeng Qiu Hanming Wu Ming Liu | 2014 | Chinese Science Bulletin2014，59，29： | 0 |
| 7 | An UPLC-MS/MS method to monitor Estriol injection and comparison of pharmacokinetic characteristics after irradiation显示文摘Objective:To develop an UPLC-MS/MS method for the accurate quantification of Estriol(E3),a new radioprotective agent,and observe the variation in pharmacokinetic characteristics of E3 after irradiation.As a hormone drug,the gender differences of E3 metabolism were also concerned here.Methods:Various chromatographic and mass spectrometric conditions of E3 were optimized.The specificity,linearity,precision and accuracy of UPLC-MS/MS method were validated.Twenty SD rats,half male and half female,were administered with intramuscular(im)injection of 2.7 mg/kg E3,and then divided randomly into two groups,sham-irradiated group(Con)and irradiated group(IR).IR group was irradiated to 7 Gy ofγ-rays.Blood samples were collected at different times post-irradiation and E3 concentrations were detected.The changes of concentration-time variation and pharmacokinetic parameters for E3 after irradiation were investigated,together with metabolic differences between male and female rats.Results:The range of the calibration curve of UPLC-MS/MS for E3 was 1.00–200.0 ng/mL.Con group reached maximum concentration(Cmax)(77.57±18.71)ng/mL at(0.68±0.29)h(Tmax)after im injection.The drug concentration-time profiles and pharmacokinetic parameters of E3 were consistent before and after irradiation.The areas under time curve(AUC0-t)of E3 were(353±74)h⋅ng/mL for Con group,and(299±74)h⋅ng/mL for IR group(P>0.05).There were also no statistical differences in pharmacokinetic parameters between female and male rats.The elimination half-lifes(T1/2)of males and females were(3.02±0.68)h and(3.01±0.42)h in Con group,and(3.64±0.51)h and(3.38±0.60)h in IR group,respectively(P>0.05).Conclusion:A rapid and sensitive UPLC-MS/MS method for determination of E3 was established.The pharmacokinetic characteristics of E3 in rat were not affected by 7 Gy irradiation and gender differences.This study provided a theoretical basis for the development and application of new radiation injury treatment drug。 | Hanming Zhang Zhiyun Meng Tong Ye Taoyun Liu Jian Li Fei Ma Ruolan Gu Xiaoxia Zhu Zhuona Wu Guifang Dou Hui Gan | 2021 | Radiation Medicine and Protection2021，2，2： | 0 |
| 8 | EIGENVALUE INTEGRAL RELATION AND STABILITY CONDITION FOR A MODE显示文摘In this paper,we point out that for a static system the eigenvalue integral relation(iσ)2I+iσΦ+Σ=0 derived from an eigenequation (?)Ψ=[(iσ)2(?)2+(iσ)(?)1+(?)0]Ψ(r)=0 only gives the suffi-ciency of condition Σ>0 for the stability of a certain mode,but it can not provide the necessity tothe condition in general.Three theorems presented in this paper show that under some conditions,Σ>0 makes the mode stable,while Σ<0 makes the mode unstable. | Zhu Ruzeng Wu Hanming(Institute of Mechanics,Chinese Academy of Sciences) | 1989 | Acta Mechanica Sinica1989，5，3： | 0 |
