A method and system for performing optical proximity correction (OPC) on an integrated circuit (IC) chip design is disclosed. The system and method of the present invention includes dividing the IC chip into a plurality of local task regions, identifying congruent local task regions, classifying congruent local task regions into corresponding groups, and performing OPC for each group of congruent local task regions.By identifying and grouping congruent local task regions in the IC chip, according to the method and system disclosed herein, only one OPC procedure (e.g., evaluation and correction) needs to be performed per group of congruent local task regions. The amount of data to be evaluated and the number of corrections performed is greatly reduced because OPC is not performed on repetitive portions of the IC chip design, thereby resulting in significant savings in computing resources and time.

The invention discloses a mesophilic sealing agent and a sealing technique of aluminum anodic oxide films and belongs to the technical field of the post sealing processing of the anodic oxide films of aluminum and aluminum alloys. The sealing agent of the invention is an aqueous solution that consists of alkali metals or salts of alkali earth metals, a complexing agent and a pH buffering agent; wherein, the concentration of the alkali metals or the salts of alkali earth metals is 5 to 15 g / L, the concentration of the complexing agent is 10 to 20 g / L,, the concentration of the pH buffering agent is 0 to 10 g / L, and the residual quantity is water; the pH value of the aqueous solution of the sealing agent is maintained between 5 and 6, the aluminum anodic oxide film is sealing processed by the sealing agent, the temperature of the aqueous solution of the sealing agent is 75 to 90 DEG C, and the soaking and sealing time lasts for 20 to 30 minutes. The sealing agent adopts the alkali earth metals or the salts of alkali metals with wide resource and low cost so as to replace heavy metal nickel salts or cobalt salts in the prior art and adopts the organic complexing agent that has biodegradability, low price and simple molecules so as to replace surface activating agents that contain giant molecules and benzene rings in the prior art, and consequently the aluminum anodic oxide film that is sealing processed by the sealing agent obtains excellent anti-pruina property, and the anti-corrosion and anti-pollution properties of the anodic oxide film of aluminum and aluminum alloys are generally improved.

The mobile terminal equipment is loaded with an automatic terminal subscriber information transmission software package. The mobile terminal equipment mainly receives or transmits information, the mobile network communication platform is used as a network communication carrier, and the mobile terminal equipment service center is able to communicate with mobile terminal equipment, identify the terminal equipment and provide personalized value-added services and also act as the access platform for the mobile network operators and other value-added services.

The present invention provides taxonomy system for enterprise data management and analysis. Building a taxonomy is based on defining taxonomy themes to solve different aspects of enterprise data management. For each theme, a taxonomy is created by classifying data related to the theme. Taxonomy nodes include enterprise data management policies and data analysis methods to be applied to data stored at the nodes. The amount of data that companies need to access and manage today is complex and voluminous. Because of computational requirements and time constraints, it is very difficult to classify and process all data. In many cases, current solutions ignore a sizable amount of data and process a small subset of it. This leads to incomplete and inaccurate results as ignored data may contain valuable information. The present invention provides taxonomies that encompass all data. Voluminous data is processed first to eliminate irrelevant data that is not related to the theme of a taxonomy. This in effect reduces the amount of data used to create the taxonomy without impacting its accuracy.
