Summary This study showed that bisphosphonate was safe and effective for the treatment of bone disorders in stage 4 chronic kidney disease (CKD) rats. Intermittent teriparatide therapy showed an anabolic action on bone even under secondary hyperparathyroidism conditions without having an adverse effect on mineral metabolism in late-stage CKD. Introduction Patients with late-stage CKD are at high...
We developed a novel through silicon via (TSV) fabrication process using dry filling of sub-micron Au particle for stack type 3D MEMS. X-ray image shows that the slurry including Au particles was uniformly filled into vias with squeegee under low pressure in short time. TSV with a diameter of 30 μm and depth of 70μm were successfully fabricated. The resistance of single TSV was 0.11 Ω. The dielectric...
Low-temperature wafer bonding using sub-μm gold particles together with wafer-level pattern transfer method has been developed. Sub-μm Au particle patterns were successfully transferred at 150°C and wafer bonding was performed at 200°C. Surface compliant performance was demonstrated by compression deformation measurement.
This paper describes wafer level vacuum packaging with sub-micron Au particles for MEMS (micro electro mechanical systems) applications. Low temperature bonding is indispensable for relevant MEMS packaging, and use of sub-micron Au particles are suitable for hermetic seal bonding. For the fabrication of hermetically sealed wafer level packaging, a base silicon wafer and a cap glass wafer were bonded...
According to the electrode theory widely accepted, the polarization resistance (R p ) of SOFC oxygen electrodes should be independent of the electrolyte resistivity (ρ). This is a natural consequence from the usual theory, since it assumes that R p is only determined by the interaction between the electrode and gas phase. However, it has been recently found that R p increases...
