    摘要: A method for evaluating reliance level of a virtual metrology system is disclosed. In this method, a reliance index (RI) and a RI threshold value are calculated by analyzing the process data of production equipment, thereby determining if the virtual metrology result is reliable. Besides, in this method, a global similarity index (GSI) and individual similarity indexes (ISI) are also provided for defining the degree of similarity between the current set of process data and all of the sets of historical process data used for establishing the conjecture model, thereby assisting the RI in gauging the degree of reliance and locating the key parameter(s) that cause major deviation.

    摘要: A generic service management system is disclosed. The generic service management system comprises a registration scheme; a search-and-execution scheme; and a detection-and-replacement scheme, used for detecting and replacing the invalid service provider, such as a semiconductor equipment manager. The present invention provides a GEV (Generic Evaluator) having the capabilities of error-detecting and data backup, and further combines Jini infrastructure and the programming technology of design by contract. The GEV archives the credit values of all the service providers for letting a client (such as a factory manager) to select a service provider having a higher credit value. The GEV periodically backups the execution status and parameters of service providers, so that, in case a service provider has errors, its backup information of execution status and parameters can be assigned to another service provider for continuously executing the unfinished job, thereby enhancing the reliability of distributed object-oriented systems. The present invention can detect abnormal behaviors, such as system crash, errors in transmitting information and degradation of performance, etc., and is suitable for use in production systems that are connected by networks, such as semiconductor manufacturing systems, optical telecommunication production systems, etc.

    摘要: An equipment management method for managing semiconductor equipment via an equipment manager. In the equipment management method, production scenario rules and equipment behavior rules are first defined respectively in a production scenario database of a configuration controller and an equipment behavior database of an equipment driver. Them, a command is received from a manufacturing execution system (MES), and is converted into a production process scenario by looking up the corresponding production scenario rule in the production scenario database. Thereafter, the production process scenario is converted into a GEI (generic equipment interface) message with a GEI message specification, and the GEI message is transmitted to the equipment driver. Then, the GEI message is converted into equipment communication messages regulated by an equipment communication protocol by looking up the corresponding equipment behavior rule in the equipment behavior database. Then, the equipment communication messages are transmitted to equipment.

    摘要: A method for providing an application cluster service (APCS) with fault-detection and failure-recovery capabilities. This method is composed of the steps of nodes clustering, invoking and detecting applications, fault-recovery of applications, detection of nodes, and node replacement. This method is applicable in a clustered environment to detect if a slave node is failed by sending a heartbeat periodically from a master node; and to detect if the master node still exists by checking if the master node stops sending the heartbeat (i.e. the master node may be failed).
