  • METHOD FOR GRAFTING SURFACE OF MEDICAL DEVICE BY USING QUATERNIZED TRIMETHYLAMINE
    Publication number: 20240165306
    Abstract: The present invention relates to a method for grafting a surface of a medical device by using quaternized trimethylamine. A catheter onto which quaternized trimethylamine has been grafted allows for the reduction of thrombus production. Therefore, the catheter having quaternized trimethylamine grafted thereto exhibits the effect of repressing thrombus production and enhancing the function of inhibiting blood adsorption and blood cell adsorption.

  • Organic polymers for bottom antireflective coating, process for preparing the same, and compositions containing the same
    Patent number: 6610457
    Abstract: A bottom antireflective coating layer is made from the compositions of organic photosensitive materials that contain isoflavone chromophore by photolithography utilizing a deep ultraviolet light source for producing a submicro-level, large-scale integrated chip. A copolymer containing an isoflavone chromophore is used as a bottom antireflective coating layer for fabricating a 64-megabit or gigabit DRAM. The antireflective coating layer enables not only the suppression of reflections of light that occur under the substrate layer but also the removal of standing waves. Consequently, a high-resolution sub-micron of a 100˜200 nm integrated circuit is able to be stably formed. Therefore, it is possible to increase the production of semiconductors.
