A processing line includes a tool adapted to process a set of wafers, and a process controller.

Abstract: A method and apparatus for providing fault detection in an Advanced Process Control (APC) framework. A first interface receives operational state data of a processing tool related to the manufacture of a processing piece. The state data is sent from the first interface to a fault detection unit. A fault detection unit determines if a fault condition exists with the processing tool based upon the state data. A predetermined action is performed on the processing tool in response to the presence of a fault condition. In accordance with one embodiment, the predetermined action is to shutdown the processing tool so as to prevent further production of faulty wafers.

Abstract: A system and method for calculating the performance of a cluster tool using a weighted configuration matrix. The system includes a computer system which maintains a database of entities corresponding to semiconductor wafer processing modules in a fab. A user "clusters" the entities, i.e., selects entities to reflect the relationship of the constituent modules physically linked together which form the cluster tool. The user also designates a main module against which the main performance events of the cluster tool, such as begin run and end run, are logged in the database. The computer system configures all of the "up" and "down" state configuration combinations of the cluster tool modules and displays the configurations for the user. The user specifies a weight for each of the configurations based upon an estimate of the performance the cluster tool while in the respective configuration relative to the performance of the cluster tool in a fully operable configuration.

Abstract: A system and method for detecting faults in wafer fabrication process tools by acquiring real-time process parameter signal data samples used to model the process performed by the process tool. The system includes a computer system including a DAQ device, which acquires the data samples, and a fault detector program which employs a process model program to analyze the data samples for the purpose of detecting faults. The model uses data samples in a reference database acquired from previous known good runs of the process tool. The fault detector notifies a process tool operator of any faults which occur thus potentially avoiding wafer scrap and potentially improving mean time between failures. The fault detector also receives notification of the occurrence of process events from the process tool, such as the start or end of processing a wafer, which the fault detector uses to start and stop the data acquisition, respectively.

Abstract: Method and system for automatically and accurately generating E10 reports based on a user-selected set of parameters, including date range, equipment and other parameters, are disclosed. In a preferred embodiment, the system of the present invention performs three primary functions; namely, a mapping function, a data extraction function and a reporting application function. The mapping function enables users to map WorkStream events into E10 defined states outside of the WorkStream database. The reporting application function provides several major functional capabilities, particularly, enabling a user to formulate restriction information, or "E10 data requests," for data extraction and reporting purposes. Each E10 data request identifies, as a function of facility (or manufacturing area), module, family and/or equipment, the equipment list for which data is to be accumulated, as well as a time period for reporting and duration type to report on.
