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.

Abstract: Disclosed is an environmentally-friendly method for enhancing mechanical properties of a high antibacterial nano dialysis paper for medical protection, includes following steps: a, preparing pulp components, and taking 40-60 parts of hardwood pulp, 10-20 parts of polyvinyl alcohol fiber, 30-50 parts of softwood pulp, 10-20 parts of cellulose fiber by mass; b, putting the hardwood pulp, the polyvinyl alcohol fiber, the softwood pulp and the cellulose fiber into a beater for beating to make a pulp, and then adding modified chitosan accounting for 1-5% of a weight of the pulp into the pulp, and defibering for 10-20 minutes at a rotating speed of 1500-2000 revolutions per minute in a defibrator; and c, carrying out papermaking with the pulp after defibering to form a dialysis paper finished product.
