Methods for manufacturing semiconductor devices are provided. First and second portions of a first metal layer are formed in a first interlayer insulating layer. A second interlayer insulating layer is formed to cover the first portion and has an opening that exposes the second portion. A dielectric layer is formed on the exposed second portion. A second metal layer is formed on the dielectric layer to fill the opening in a capacitor region. A via contact hole to expose the first portion is formed in the second insulating layer. A third metal layer is formed in the via contact hole. A third interlayer insulating layer is formed on the second interlayer insulating layer. Contact holes to expose the second metal layer and the third metal layer are formed in the third interlayer insulating layer. A fourth metal layer is formed in the contact holes.

This invention relates to a process for preparing styrene-butadiene rubber or butadiene rubber with both ends of the polymer chain modified by solution polymerization, wherein styrene-butadiene rubber or butadiene rubber is polymerized using a monofunctional anionic polymerization initiator modified with amines or the like, and then the active anion at the ends of the polymer chain is reacted with the commonly available modifier. Unlike a bifunctional initiator that shows a poor solubility in a nonpolar solvent, an increase in viscosity and loss of modification efficiency induced by impurity, styrene-butadiene rubber or butadiene rubber by solution polymerization can be prepared using the modified anionic polymerization initiator of the invention.

A translation-memory application method for automatic translation includes: generating TM-expanded forms by applying TM expansion rules respectively to source sentences whose morphemes have been analyzed; storing in an expanded TM database translated sentences corresponding to the generated TM-expanded source sentences; analyzing morphemes if an input sentence does not match any of the source sentences stored in basic TM database; generating a TM-expanded form by applying pertinent ones among the TM expansion rules to the input sentence whose morphemes have been analyzed; and producing, if the TM-expanded input sentence matches one of the TM-expanded source sentences stored in the expanded TM database, a translated output corresponding to the matched TM-expanded source sentence.
摘要:
An image forming apparatus and a method of controlling the same which may prevent brokenness of data displayed on a display are provided. The image forming apparatus performs a read operation on data previously stored at a specific address of a storage unit of an LCD module or on data stored through a write operation. The image forming apparatus compares data acquired through the read operation and known data. If the data acquired through the read operation and the known data are different, the image forming apparatus adjusts a setup time of an enable signal to prevent brokenness of data due to incorrect timing of the enable signal.
摘要:
The present invention relates to a lithium-containing metal composite oxide comprising paramagnetic and diamagnetic metals, which satisfies any one of the following conditions: (a) the ratio of intensity between a main peak of 0±10 ppm (I0ppm) and a main peak of 240±140 ppm (I240ppm), (I0ppm/I240ppm), is less than 0.117·Z wherein z is the ratio of moles of the diamagnetic metal to moles of lithium; (b) the ratio of line width between the main peak of 0±10 ppm (I0ppm) and the main peak of 240±140 ppm (I240ppm), (W240ppm/W0ppm), is less than 21.45; and (c) both the conditions (a) and (b). The peaks of the lithium-containing metal composite oxide are obtained according to the 7Li—NMR measurement conditions and means disclosed herein.
