Abstract:
Disclosed are a display filter, a display device comprising the filter and a production method for the filter. The disclosed display filter comprises a base section and a pattern section which is formed on the base section. The pattern section is formed from an adhesive material comprising metallic powder. The metallic powder is included at 10-30 parts by weight relative to the pattern section. Thus, bright room contrast can be improved by blocking light coming from outside, and electromagnetic waves generated from within a panel can be reduced.

Abstract:
A method of fabricating a nonvolatile memory device includes providing a substrate having active regions defined by a plurality of trenches, forming a first isolation layer on the substrate having the plurality of trenches, forming a sacrificial layer on the first isolation layer to fill the trenches, the sacrificial layer including a first region filling lower portions of the trenches and a second region filling portions other than the lower portions, removing the second region of the sacrificial layer, forming a second isolation layer on the first isolation layer and the first region of the sacrificial layer, forming air gaps in the trenches by removing the first region of the sacrificial layer, and removing a portion of the first isolation layer and a portion of the second isolation layer while maintaining the air gaps.
Abstract:
The present invention relates to mutant microorganisms having improved productivity of branched-chain amino acids, and a method for producing branched-chain amino acids using the mutant microorganisms. More specifically, relates to mutant microorganisms having improved productivity of L-valine, which are produced by attenuating or deleting a gene encoding an enzyme involved in L-isoleucine biosynthesis, a gene encoding an enzyme involved in L-leucine, and a gene encoding an enzyme involved in D-pantothenic acid biosynthesis, and mutating a gene encoding an enzyme involved in L-valine biosynthesis, such that the expression thereof is increased, as well as a method for producing L-valine using the mutant microorganisms. The inventive mutant microorganisms produced by site-specific mutagenesis and metabolic pathway engineering can produce branched-chain amino acids, particularly L-valine, with high efficiency, and thus will be useful as industrial microorganisms for producing L-valine.
