One of the key enablers for the successful integration of 3-d interconnects using the Through-Silicon Via (TSV) schemes is the control of the mechanical stresses in the Cu TSV itself as well as in the surrounding silicon substrate. The synchrotron-sourced X-ray microdiffraction technique has been recognized to allow some important advantages compared to other techniques in characterization of the mechanical stresses in a TSV sample. This approach have been used to study Cu TSV samples from SK Hynix, Inc. earlier as well as more recently from SEMATECH, and we have found interesting differences in the stress states of the Cu TSV. We proposed a possible explanation of the observed differences. This fundamental understanding could lead to improved stress control and hence reliability in the Cu TSV samples, as well as to reduce its impact to the silicon electron mobility and hence to device performance in general.

In this paper, the full-speed range path following system is proposed regardless of side-slip angle caused by lateral and inertia force in the high speed driving. In order to have robustness about model parameter error, the proposed system is designed according to the back-stepping control algorithm. In order to have control performance in full speed range, both kinematic and dynamic model is used, and to avoid the frequent transition between kinematic and dynamic based control mode, the hysteresis characteristics is applied. The performance of the proposed algorithm is evaluated by simulation and real-car test in the proving ground with 1km straight road and 30m radius curved road.

Effects of clean chemical pH on Pr/FM and HM defects for W-CMP are examined. Oxalic acid, dIW, and a QAC-based basic chemicals are evaluated for their Pr/FM cleaning performance and hollow metal generation. Basic clean chemistry is demonstrated to be more efficient for Pr/FM removal but more prone to HM defects. AFM and XPS surface analyses conducted on post W-CMP wafers help discern the cleaning mechanism for W-CMP.

This study describes the lessons learned from designing, deploying and analysing the results from different travel satisfaction survey tools which measures the travellers’ door-to-door travel satisfaction. The travel satisfaction measurement survey tools tested consisted of two types of smartphone applications (a satellite navigation app and a game app), an on-line survey, a paper-based semi-structured questionnaire and a focus group questionnaire. Each of the measurement tools comprised the same set of basic questions, but in different formats, aimed at exploring the pros and cons of each tool among different groups of travellers. The data collection was carried out at eight different European cities and five FIA motorist networks. 5,275 valid responses were gathered from the survey. Further analysis results show that different survey methods performed better in different sites. The satisfaction that was gathered via main trip leg does not necessarily correspond with overall satisfaction of the door-to-door journey. The results of this study highlight the need for more inclusive, complete, door-to-door, travel survey measurements.

An inverse metal only reflectarray antenna consisting of multiple variable height conducting cells is designed at millimeter wave frequency. All reflecting elements are only made up of metal so that there is no dielectric loss in the antenna. Simulation result shows that the radiation efficiency of designed antenna is comparable with conventional parabolic reflector.

A new testing method for investigating the shear-mode fatigue crack growth behavior in hydrogen environment

Journal of Physics: Conference Series 2017年第1期842卷

Ball bearing is widely used in a variety of machines including the transportation equipments of the automobiles and airplanes. Flaking failure is a common problem for ball bearing and it is caused by shear-mode fatigue crack growth under cyclic shear stress. Further, it is known that the premature flaking is attributed to the combined effect of hydrogen penetration into the material and cyclic shear stress during the operation. Therefore, in order to ensure the integrity of ball bearing, it is necessary to clarify the effect of hydrogen on shear-mode fatigue crack growth behavior, in particular, the threshold behavior. The evaluation of the shear-mode crack growth behavior is not easy because mode I crack branching occurs easily. Our previous studies revealed that it is required to apply static compression in the direction of specimen axis to attain a stable shear-mode fatigue crack growth. In addition, successive hydrogen supply to the specimen is essential for the evaluation of hydrogen effect on the fatigue threshold because hydrogen emits from the specimen during the fatigue test. In other words, the hydrogen-precharging method, commonly used for the research on hydrogen embrittlement, is not appropriate for the evaluation of fatigue threshold. In this study, to solve these problems, we have developed a novel, easy-to-use experimental method to evaluate the threshold behavior of shear-mode fatigue crack in the presence of hydrogen. The fundamental principle of the method is introduced in this paper.
