Silicon interposers enable advanced package architectures through the integration of multiple die and passive components onto a single silicon substrate, while offering high interconnect density and low thermal expansion mismatch. This paper will describe the processing and characterization of copper-filled through silicon vias (TSVs) for Si interposers and related three-dimensional wafer-level packaging...
Alcohol consumption and exposure to stressful life events activate similar neural pathways and thus result in several comparable physiological and behavioral effects. Alcoholics in treatment claim that life stressors are the leading cause of continued drinking or relapse. However, few studies have investigated the interactive effects of stress and alcohol on cognitive behavior. The effects of restraint...
To test whether signal transduction proteins that mediate stress may be used to detect responses of embryos to different media in a prospective randomized study. Controlled laboratory study. None. None. Mouse embryos isolated at E3.5 (3.5 days after fertilization) or E1.5 were cultured in different media for 24 hours or 72 hours, respectively. Expression of p38 mitogen activated protein...
As a result of the extensive studies of high-field conduction and flashover in dielectric liquids it is becoming clear that the mechanism of electrical breakdown in such materials is related to the pre-breakdown charge flow. At present it is not known whether the current gives rise to significant heating such that failure occurs due to a thermal run-away1 or whether space-charge accumulation due to...
