Abstract: A semiconductor device includes a semiconductor substrate having an active region defined by an isolation layer, a gate line defining a bit line contact region in the active region and extending in one direction, and a dielectric layer covering the semiconductor substrate and the gate line formed in the semiconductor substrate. The semiconductor device is provided with a bit line contact hole formed in the dielectric layer and exposing the bit line contact region. In order to alleviate a self-aligned contact (SAC) fails caused by a conductive material remaining in a contact hole, the semiconductor device contains a bit line contact spaced apart from a sidewall of the bit line contact hole and formed in the bit line contact hole.

Abstract: There is provided a color cathode-ray tube comprising a panel having a fluorescent plane formed on the inner face thereof, and a shadow mask arranged at the inner side of the panel having a predetermined distance therefrom, in which the shadow mask has an effective area in which electron beam passage holes are formed and a non-effective area surrounding the effective area, and at least one half etching line is formed at the non-effective portion of the shadow mask. Accordingly, shocks due to vibration of the cathode-ray tube are absorbed not to transmit to the shadow mask, improving the curved surface supporting strength of the shadow mask.

Abstract: The disclosed cathode-ray tube has a pyramidal yoke mounting part defined to extend from a joint with the neck to at least the end of a deflection yoke on the side of the screen, the yoke mounting part including: an inside profile having a form protruding towards a tubular axis in the direction of major and minor axes based on a diagonal axis so as to have a functional relation with a deflection angle; and an outside profile having a rectangular form with respect to the major and minor axes, the outside profile having a ratio of a maximum thickness to a minimum thickness on the same axis being either of the minor or major axis in the range from 1.0 to 1.5. It satisfies a relation 0.7<Rov/Roh≦1.0, wherein Roh is a radius of outer curvature in the direction of the major axis and Rov is a radius of outer curvature in the direction of the minor axis.
