    摘要： A method and system for protecting silicon IPs from unauthorized use, transfer and sale, and for hiding confidential technology information contained in silicon IPs is described. The method and system create a content-encrypted silicon IP layout database from its original layout database. Both the layout database may be GDSII files, OASIS files, or other format layout database file, in which multiple records sequentially build the layout database. In accordance with one preferred embodiment, first, the original layout database is parsed and saved as sequential records in the memory. Next, the structure records, which construct structures in the original layout database, are selected from the saved records. Once the structure records have been selected, the data of the structure records may be compressed with using a public compressing method, and may be encrypted with using a public cryptography algorithm. Next, each byte of the data after compression and encryption is mapped to one or two printable ASCII characters for building up multiple new text element records in a new structure. Finally, the newly created structure records replace the selected structure records in the original layout database to create the content-encrypted silicon IP layout database.

    摘要： A system for calculating electrical properties of features to be created in an integrated circuit. All or a portion of a desired layout design is corrected for photolithographic or other process distortions using one or more resolution enhancement techniques. A simulated layout image of a corrected layout is used as an input to a field solver program that calculates the electrical properties of the features as they will be printed on a wafer.

    摘要： A process of microcellular foam molding an article includes using a modifier to modify properties of amorphous PLA, pouring the modified amorphous PLA into a high pressure vessel, dissolving an SCF in the high pressure vessel to impregnate the modified amorphous PLA in the high pressure vessel which is configured to allow the SCF to effuse through, forming foamed pellets, conveying the foamed pellets to a mold in a second vessel filled with water or oil, heating the second vessel, and cooling the second vessel until a foamed article is finished in the mold.
