The Hall signals of Ga and Hg metals at liquid and solid states obtained through a new simultaneous method have been examined and compared with those of amorphous metals and solid state semiconductors of Si and InSb single crystals. Liquid metals of Hg and Ga of 5 N pure, para and ferromagnetic films of amorphous iron, and single crystals of Si and InSb(More)
For the purpose of shortening turn around time (TAT) and costs of phase-shifting mask (PSM) fabrication, we proposed a new concept of PSM composed of an opaque pattern substrate and a phase shifter substrate. It was considered that this PSM has the disadvantage of high wave-front aberration. In order to solve this problem, we have designed a high NA (0.75),(More)
A new method of plotting the impurity profile is described. It makes efficient use of the advantage of an operational amplifier and the nonlinearity of the junction capacitance in a semiconductor. When two small ac signals are applied to the inverting input terminal of the operational amplifier, intermodulation arises due to the nonlinearity of the junction(More)
Diamagnetic lanthanide(III) complexes with an imino nitroxide radical IM2py [2-(2 -pyridyl)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazol-1-oxyl], [Ln(hfac)3(IM2py)] (Ln = Y and Lu; hfac = hexafluoroacetylacetonate), exhibit 1H NMR chemical shifts for the pyridyl protons of the coordinated IM2py suggesting it behaves as if it were diamagnetic. To a series of(More)
We present a new exposure method to achieve super resolution of a projection lens. The idea is based on a cover glass inserted between an optical lens and image plane. We have designed a projection lens system using a cover glass. It has found that the resolution of the projection pattern can be improved by use of a cover glass under the condition that the(More)
