  • Publication number: 20140228314
    Abstract: Disclosed is a method for preparation of a chitosan oligosaccharide composition capable of increasing a content of disaccharide in chitosan oligosaccharide with excellent effects of reducing HbAlc and blood glucose as well as excellent thermal stability. The method for preparation of a chitosan oligosaccharide composition includes: adding chitosan to distilled water to swell the chitosan; firstly treating the chitosan with a chitosanase to prevent the chitosan solution from becoming a state of being viscose, then, adding an organic acid to a mixed solution of the chitosan and chitosanase at a predetermined time interval bit by bit over several additions; allowing mutual reaction between the chitosan, chitosanase and organic acid; and inactivating the chitosanase to obtain the chitosan oligosaccharide composition. Further, a medicine and/or health supplement food which is effective in preventing and treating diabetes, including at least 40% of disaccharide without monosaccharide, is also disclosed.

Residuals of the first insulation layer are passively formed into a first device isolation pattern on the first area. The first insulation layer is removed from the second area of the substrate and a semiconductor layer is formed on the second area of the substrate by a SEG process. The semiconductor layer on the second area is patterned into a second active pattern including a recessed portion and a second insulation pattern in the recessed portion is formed into a second device isolation pattern on the second area.

  • Patent number: 8343851
    Abstract: A wafer temporary bonding method using silicon direct bonding (SDB) may include preparing a carrier wafer and a device wafer, adjusting roughness of a surface of the carrier wafer, and combining the carrier wafer and the device wafer using the SDB. Because the method uses SDB, instead of an adhesive layer, for a temporary bonding process, a module or process to generate and remove an adhesive is unnecessary. Also, a defect in a subsequent process, for example, a back-grinding process, due to irregularity of the adhesive may be prevented.
