Aiming at the capturing difficulties for space satellites caused by pose error of the manipulator, a design method of modular reusable locking-release devices based on error field analysis is proposed in this paper. Firstly, error field of the captured trunnion at the bottom of the satellite is analyzed based on the pose error of manipulator terminal and the trajectory of the trapping component is...
Scaling down the complementary metal oxide semiconductor field effect transistors (COMS FET) requires involvement of High K (HK) metal gate technology in sub 45nm nodes. HK enables significant lower leakage at similar effective oxide thickness (EOT) to SiO2 by effective suppression of direct tunneling. However, stress induced leakage current (SILC) and defects in the ultrathin interlayer in HK stack...
Low-k/ultra-low-k dielectric is expected to have large-scale implementation in the manufacturing of modern advanced IC technology nodes. The reliability performance of a low-k dielectric must meet the given target lifetime based on semiconductor electrical requirements. Reliability test structures are specifically devised in this paper. We proposed a series of fundamental improvements on test structures...
Automatic sleep pattern analysis has been a very important research issue for the diagnosis in sleep medicine. This paper proposes a nonintrusive sleep/wake identification method based on computer vision approach to extract visual sleep activity and sleep/wake patterns. This approach is robust to noise, contrast and illumination variations of infrared videos. The proposed method extracts body motion...
In the redundant system, Common Cause Failure (CCF) can result in failures of more than one module. Human Error is one of the most important causes among all the causes of CCF. Human factor diversity is an effective method against CCF due to human error. Although there is clear evidence that diversity can bring benefits, these benefits can be difficult to quantify. The current methods of human reliability...
How to survive and grow has always been a serious problem faced by the small and medium sized enterprises (SMEs) on a B2B platform. A lot of researches in entrepreneurship field have proved the positive effects of entrepreneurial orientation on firms' performance, but few researchers studied how entrepreneurial orientation influences performance. Based on the institutional theory, this paper introduces...
Common cause failures (CCF) are a serious threat to redundant system reliability. It is therefore important to quantify and model CCF in reliability assessments. Design diversity has long been used to protect redundant systems against CCF. However, it is difficult to quantify the effects of diversity on system reliability. Therefore, a novel method based on Root Cause (RC) and Coupling Factor (CF)...
GAA-MNC TFT shows higher on-current, higher mobility, steeper subthreshold swing and lower threshold voltage than CP TFT. In this letter, we study in view of PBTI and NBTI of GAA-MNC TFT. Under room temperature, the PBTI or NBTI of GAA-MNC TFT show more serious degradation than CP TFT. In order to improve reliability, we use plasma to passivate defect in the oxide/channel interface.
This paper combined the finite element method with theory of reliability design and applied the PDS module of ANSYS to establishing 3D parameterized model of shield cutter. What's more, it compiled the APDL command flow and obtained the reliability documents to analysing the reliability of shield cutter. It can be obtained the reliability of shield cutter and influence degree of different parameters...
Aiming to study dynamic mechanical properties of the transparent silicone resins for LEDs packaging and the effects of dynamic mechanical properties on the reliability of high power LEDs, dynamic mechanical analysis (DMA) has been adopted to study one silicone resin used for packaging high power white light LEDs. The viscoelastic behavior of silicone resin was obtained from multi-frequencies dynamic...
This paper reports the first direct experimental measurement of electromigration-induced stress in aluminum interconnects using a series of micro-rotating stress sensors. The build up of stress gradients in interconnect metallization concomitant with back stress have been previously investigated theoretically, but experimental verification using optical or X-ray techniques has proven more difficult...
