Abstract

The complexity of manufacturing process data has made it more challenging to extract useful insights. Data-analytic solutions have therefore become essential for analyzing and optimizing manufacturing processes. Path modeling, also known as structural equation modeling, is a statistical approach that can provide new insights into complex multivariate relationships between process variables from different stages of the manufacturing process. The incorporation of expert process knowledge and subsequent interpretation of model results can facilitate communication between stakeholders, promoting lean manufacturing and achieving the sustainability goals of Industry 5.0. This paper describes the use of a path modeling algorithm called Process Partial Least Squares (Process PLS) to gain new insights into the relationships between equipment data from several machines within the semiconductor manufacturing process. The methods used in this study can assist manufacturers in understanding the relations between different machines and identify the most influential variables that may be used to develop soft-sensors.
