Abstract: A method and system of monitoring a processing system and for processing a substrate during the course of semiconductor manufacturing. As such, data is acquired from the processing system for a plurality of observations, the data including a plurality of data parameters. A principal components analysis (PCA) model is constructed from the data and includes centering coefficients. Additional data is acquired from the processing system, the additional data including an additional observation of the plurality of data parameters. The centering coefficients are adjusted to produce updated adaptive centering coefficients for each of the data parameters in the PCA model. The updated adaptive centering coefficients are applied to each of the data parameters in the PCA model. At least one statistical quantity is determined from the additional data using the PCA model. A control limit is set for the statistical quantity and compared to the statistical quantity.

Abstract: A method includes providing a bus, and providing a means for testing the bus for proper termination resistance during normal operation of the bus.

Abstract: The present invention provides a method and apparatus for multivariate fault identification and classification. The method includes accessing data indicative of a plurality of physical parameters associated with a plurality of processed semiconductor wafers and providing at least one summary report including information indicative of at least one univariate representation of the accessed data and at least one multivariate representation of the accessed data.

Abstract: An anti-virus system provider distributes an e-mail identifying content filtering rule seeking to identify e-mail messages suspected of containing an item of malware from a central source (20) to users (2). This distribution may be by an e-mail message itself which is appropriately signed and encrypted. At the user system (2), the received e-mail identifying content filtering rule is extracted from the e-mail message and added to the content filtering rules (18) being applied within that user system. In this way, malware which is distributed by e-mail may be identified by characteristics of its carrier e-mail rather than characteristics of the malware itself which not yet have been properly analyzed or the mechanisms for detecting such characteristics of the malware itself not yet put in place.

Abstract: A method of automatically configuring an Advanced Process Control (APC) system for a semiconductor manufacturing environment in which an auto-configuration script is generated for executing an auto-configuration program. The auto-configuration script activates default values for input to the auto-configuration program. The auto-configuration script is executed to generate an enabled parameter file output from the auto-configuration program. The enabled parameter file identifies parameters for statistical process control (SPC) chart generation.

Abstract: An apparatus, method and system to enable dynamic replication of Web servers across a wide area in response to access patterns by Web clients as well as in response to customer requests. The method for dynamically replicating one or more parent nodes on a network in response to a user request by a policy manager. The policy manager transmits the user request to an event module. The event module transmits the user request to a data consistency module, wherein the data consistency module maintains integrity of the data on the parent node. The event system communicates with a resource management module to ensure proper utilization of network resources, and transmits the routing request to a request routing module for appropriately balancing the network load. The request routing module is capable of providing optimal routing based on the network resources.

Abstract: In general, an electrically operated car jack is described. A typical embodiment includes a base frame or housing that is adapted to be placed on the ground underneath the automobile to be lifted. The housing includes motors connected to drive arms connected to a load bridge and plate. The bridge is typically mounted within the drive arms by rods located within slots on the arms enabling the bridge to move upward and downward while being retained within the drive arms. Typically, the motors are operated by the car's battery. The drive arms typically include drive wheels that rotate oppositely and are coupled together by a coupler in an X-configuration that assures the coupler moves uniformly. The motors drive the arms, lifting and lowering the load bridge which lifts and lowers the automobile. The jack can be operated by remote control.
