    摘要: A memory cell of a dynamic storage device is composed of a MOSFET and a capacitor. On a single semiconductor substrate, a plurality of such memory cells are regularly arranged so as to form a plurality of columns, with the result that they constitute a memory cell array or a memory cell mat. The capacitor for the memory cell is made up of a semiconductor region of the type which possesses a conductivity opposite to that of the semiconductor substrate, and a conductor film which is formed of polycrystalline silicon or the like on the semiconductor region through a comparatively thin insulating film. The areas of the capacitors in the memory cell column situated at an end portion of the memory cell mat are made larger than those of the capacitors of the memory cells at an inner or central portion of the memory cell mat. The memory cells at the end portion of the memory cell mat come to have information holding times equivalent to those of the memory cells at the central portion of the memory cell mat.

    摘要: A sample CD measurement system adapted for measuring the CD of a measurement portion accurately even in the case where the shape of the measurement portion and the direction of measurement are arbitrary. Before the CD measurement, a measurement reference image corresponding to the measurement portion is registered in a computer and controller. At the time of the CD measurement, the measurement reference image is read and compared with an image of the measurement portion to thereby obtain a difference in shape between the image of the measurement portion and the measurement reference image on the basis of a result of the comparison to thereby obtain the CD of the measurement portion on the basis of the difference in shape.

    摘要: A pattern shape inspection apparatus for displaying a specimen image on a display apparatus, and inspecting a pattern shape of the specimen image includes a memory for memorizing a reference image corresponding to an observation region and a display for simultaneously displaying the reference image and the specimen image. At least one of the image parameters of the specimen image and the reference image is corrected to aid in the comparison.

    摘要: Disclosed herein is a microwave dielectric ceramic composition which comprises a compound represented by the formula BaO.multidot.xTiO.sub.2 (where 3.7.ltoreq.x.ltoreq.4.5) which is incorporated with 1.0-10 wt. % Ba.sub.3 Ti.sub.12 Zn.sub.7 O.sub.34 and 2-8 wt. % Ta.sub.2 O.sub.5. It has well-balanced performance owing to a Q value not less than 8000 (at 4.5 GHz), a relative permittivity .epsilon. not less than 31, and a practical temperature coefficient in the range of -15 to +10 ppm/.degree.C. It may be further incorporated with 0.1-0.4 wt. % MnO.sub.2 for improved sinterability in addition to the above-mentioned performance.
