  • Patent number: 9698056
    Abstract: A method of manufacturing a semiconductor device includes providing pre-conductive lines and post-conductive lines for forming a first logic cell and a second logic cell, which are adjacent to each other, and a dummy cell and a third logic cell, which are adjacent to each other. A first conductive line, adjacent to the second logic cell, from among conductive lines of the first logic cell is spaced a first reference distance apart from a second conductive line, adjacent to the first logic cell, from among conductive lines of the second logic cell. A dummy line, which is adjacent to the third logic cell, from among conductive lines of the dummy cell is spaced a second reference distance apart from a third conductive line, which is adjacent to the dummy cell, from among conductive lines of the third logic cell. The second reference distance is greater than the first reference distance.

  • Publication number: 20170016032
    Abstract: The present invention relates to a method for producing 1,3-propanediol using a mutant microorganism lacking a 2,3-butanediol synthetic gene, and more particularly to a mutant microorganism wherein a gene encoding lactate dehydrogenase and a gene encoding an enzyme which is involved in 2,3-butanediol synthesis are deleted in a microorganism having the ability to produce 1,3-propanediol from glycerol and wherein a gene encoding pyruvate decarboxylase and a gene encoding aldehyde dehydrogenase are introduced or amplified, and to a method of promoting the production of 1,3-propanediol while inhibiting the production of 2,3-butanediol by using the mutant microorganism. The use of the glycerol-fermenting mutant microorganism according to the present invention can significantly increase the production of 1,3-propanediol while minimizing the production of 2,3-butanediol.

  • Patent number: 9090919
    Abstract: The present invention relates to a novel method of producing 3-hydroxypropionic acid from glycerol, and more particularly to a method of producing 3-hydroxypropionic acid by culturing in a glycerol-containing medium a mutant microorganism obtained by amplifying an aldehyde dehydrogenase-encoding gene in a microorganism having the abilities to produce coenzyme B12 and produce 3-hydroxypropionic acid using glycerol as a carbon source. The present invention enables the fermentation of glycerol even under microaerobic or aerobic conditions without having to add coenzyme B12. Thus, the invention will be very suitable for the development of biological processes for producing large amounts of 3-hydroxypropionic acid.
