    摘要: A ferroelectric element is provided that can be highly densely integrated having a high Pr and a small Ec by using a ferroelectric thin film of the perovskite structure. A large distortion is imparted to the crystalline lattices of a ferroelectric thin film of the perovskite structure by using in combination elements having dissimilar ionic radii for the A-site that constitutes crystalline lattices, for the B-site and for the C-site that produces polarization, in order to obtain a ferroelectric element of a structure in which the ferroelectric thin film exhibiting a high spontaneous polarization and a small coersive electric field is sandwiched by the electrodes.

    摘要: A ferroelectric element having a high Pr and a low Ec and having a good withstand voltage, which is in the form of a thin film using a ferroelectric layer containing insulating particles, is provided. The ferroelectric layer containing the insulating particles is effective to suppress leakage current caused through grain boundaries of crystals, and hence to exhibit a high Pr and a low Ec and a good withstand voltage. The ferroelectric element has a structure in which such a ferroelectric layer in the form of a thin film is sandwiched between electrodes. By incorporating the ferroelectric element in a field effect transistor structure, it is possible to realize a highly integrated semiconductor device for detecting reading or writing.

    摘要: An anti-reflection film is in the form of a laminated film composed of an uppermost film layer containing coloring matter having an absorbing peak in a region near the infrared region of 700 nm-900 nm, or coloring matter having an absorbing peak in a region of 600 nm-700 nm, or both of the above coloring matter, and the next film layer to the uppermost layer containing coloring matter having an absorbing peak in a region of 500 nm-600 nm. The anti-reflection film utilizes a variation of the refractive indexes based on abnormal refractive index dispersion by the films containing the coloring matter. The anti-reflection film having a low reflectivity all over the visible light region can be manufactured by utilizing the abnormal refractive index dispersion of the next layer to the uppermost layer caused by an absorption of red coloring matter and a balance with the refractive indexes of the uppermost layer containing red color matter having an absorption in the region near the infrared wavelength, or blue coloring matter, or both of the above coloring matter. Furthermore, red coloring matter, having an absorbing peak in the region of 500 nm-600 nm and contained in the next layer to the uppermost layer, absorbs side bands of green and red, and accordingly, color purity is improved.
