Calibration establishes and standardizes common units of measurement for commerce and scientific study. Through calibration the measured item or sample is related to items or samples with known properties, the standards. Statistical methods are typic

Trace contamination components often have distributions that are skewed to the right and show varying degrees of censoring. In order to meet customer requirements, control charts must account for these factors while maintaining a fixed type I error a

Failure to appropriately account for the nonconstant variance in the calibration data often leads to unreasonable estimates of calibration parameters. In this paper, we contrast the normal regression-based approach (ordinary least squares) as applied

The control of particulate contamination is integral to many semiconductor manufacturing processes. In these processes, particle contamination levels are measured and compared with performance standards and statistically analyzed to determine the pro

The traditional method of estimating the weight of multiple objects is to obtain the weight of each object individually. We demonstrate that the precision and accuracy of these estimates can be improved by using a weighing scheme in which multiple ob

Linewidth roughness (LWR) is a major challenge for 90nm node and below. As feature sizes decrease, the reliable measurement, statistical comparison and interpretation of LWR data become increasingly important. The reliability of all LWR statistical a
