  • Optical proximity correction device and method
    Patent number: 11934106
    Abstract: An optical proximity correction (OPC) device and method is provided. The OPC device includes an analysis unit, a reverse pattern addition unit, a first OPC unit, a second OPC unit and an output unit. The analysis unit is configured to analyze a defect pattern from a photomask layout. The reverse pattern addition unit is configured to provide a reverse pattern within the defect pattern. The first OPC unit is configured to perform a first OPC procedure on whole of the photomask layout. The second OPC unit is configured to perform a second OPC procedure on the defect pattern of the photomask layout to enhance an exposure tolerance window. The output unit is configured to output the photomask layout which is corrected.

  • Oligomer-contained nanoparticle complex release system
    Patent number: 9326938
    Abstract: An oligomer-contained nanoparticle complex is provided. The oligomer-contained nanoparticle complex of the invention comprises (a) a nanoparticle, (b) a polymer with high molecule weigh, (c) a target molecule, (d) an oligomer, wherein the oligomer is crosslinked with the polymer by the intermolecular hydrogen bonds or electron bonds, and e) a space for active substances, wherein the space for active substances is encapsulated by the nanoparticle. The oligomer-contained nanoparticle complex of the invention has the high stability and fast drug release rate, and would not be largely accumulated in normal tissues. The invention also provides a method for preparing the oligomer-contained nanoparticle complex and the method for releasing drug.
