We constructed a (3)He magnetic force microscope operating at the base temperature of 300 mK under a vector magnetic field of 2-2-9 T in the x-y-z direction. Fiber optic interferometry as a detection scheme is employed in which two home-built fiber walkers are used for the alignment between the cantilever and the optical fiber. The noise level of the laser(More)
We have investigated pad open failure of data line. To verify the mechanism of DPO failure, we designed the new method included in CCD camera and driving circuit and successfully achieved the failure images. The DPO procedure was divided into three steps. First, side wall of Cu film was exposed to Cl plasma and then CuClx compounds formed on surface of Cu(More)
