Yield patrolling system

A yield patrolling system, which monitors production yield of a manufacturing line, has at least one product measurement and test device. The product measurement and test device measures yield determining parameters of product at completion of process steps executed by equipment within the manufacturing line. The system further has a test database in communication with the product measurement and test device to receive and retain the measured yield determining parameters. A statistical calculator is in communication with the test database to receive the measured yield determining parameters. The statistical calculator then calculates from the measured yield determining parameters production yield statistics indicating an amount of the product being fabricated on the manufacturing line. A yield-warning device is in communication with the statistical calculator to receive the production yield statistics and to provide a yield warning alert to a responsible person indicating that the manufacturing line is not fabricating product with a sufficient yield. Further, a yield information interface receives a compilation of the production yield statistics for each process step from the statistical calculator.

Process Quality Predicting System and Method Thereof

The invention discloses a process quality prediction system and a method thereof. When a processing apparatus performs a process on a target, the process is measured by a measurement apparatus to receive a process value. The process value and several previous quality data collected from the measurement apparatus are used to predict the quality of the product which is processing inline. The method is composed of a moving window, a stepwise regression scheme and an analysis of covariance (ANCOVA). The drift and shift of process are overcome by the moving window. A key variable set is selected by the stepwise regression scheme and a virtual model is identified by the analysis of covariance.

Abnormality detection system and method of detecting abnormality

An abnormality detection system includes a measurement unit, a decision unit, an alarm unit, and storage units, and serves to detect the abnormality in a control characteristic value of a plurality of products manufactured on the same production line. The decision unit receives the control characteristic value stored in the storage unit, and decides whether an abnormality exists, based on that value. More specifically, the decision unit decides that the control characteristic value is abnormal when, with respect to m (m is a natural number) pieces of the products that are consecutively manufactured, an absolute value of a difference in control characteristic value between each of the products and another manufactured immediately before the former is equal to or less than a predetermined constant.

Fuzzy reasoning model for semiconductor process fault detection using wafer acceptance test data

System and method for detecting suspicious process faults. A preferred embodiment comprises determining a strength relationship between wafer acceptance test (WAT) parameters and process steps. The strength relationships indicate the affect of a failed process step on the value of a WAT parameter. Thus, if a WAT parameter is not within the parameters set in the WAT, then the suspicious process steps that caused the failure are the process steps that had a strength relationship with the failed WAT parameter. Furthermore, in a preferred embodiment, negative inferences are determined and utilized to determine a degree of suspiciousness. The degree of suspiciousness is used to determine a total degree of suspiciousness.
