The low temperature permanent wafer bonding is studied on the plasma enhanced chemical vapour deposited dielectrics. Three types of dielectric material (SiOx, SiOxNy, SiCxNy) were prepared by the conventional CMOS interconnection process which includes the thermal annealing and chemical mechanical polishing step. The plasma treatment generated by different(More)
We demonstrated fully automated in-line atomic force microscopy (AFM) for local height variation monitoring solution. Two use cases, which are local variation of SADP Fin height and oxide recess height in Fin reveal process and that of Cu nail protrusion and Cu pad recess height in wafer-to-wafer hybrid bonding process were evaluated in order to evaluate(More)
Some effects of irradiation on time-dependent accretion-disk models for black hole X-ray novae are presented. Two types of irradiation are considered: direct irradiation from the inner hot disk and indirect irradiation as might be reflected by a corona or chromosphere above the disk. The shadowing effect of the time-dependent evolution of the disk height(More)
We evaluate the exposure during nadir observations with JEM-EUSO, the Extreme Universe Space Observatory, on-board the Japanese Experiment Module of the International Space Station. Designed as a mission to explore the extreme energy Universe from space, JEM-EUSO will monitor the Earth’s nighttime atmosphere to record the ultraviolet light from tracks(More)
The most plausible mechanism for triggering the outburst of black hole candidate X-ray transients is the ionization thermal instability. The disk instability models can give the observed mass flow in quiescence, but not the X-ray spectrum. Self-irradiation of the disk in outburst may not lead to X-ray reprocessing as the dominant source of optical light,(More)
