Speech Title: Modelling and Optimisation of Batch Processes Using Machine Learning Techniques
Abstract: Batch processes are suitable for the agile manufacturing of high value added products, such as specialty polymers, pharmaceuticals, and bio-products. In contrast to continuous processes, batch processes have strong nonlinear behaviour and always operated in transient states. A further difficulty in batch process control is that product quality variables usually cannot be measured on-line and can only be obtained through laboratory analysis after a batch has finished. This talk presents several robust neural network based data driven modelling, inferential estimation, and reliable optimal control methods for batch processes. Bootstrap aggregated neural networks have enhanced model generalisation capability and can also provide model prediction confidence bounds. One of the most important issues of empirical model based batch process optimal control is that the calculated optimal control profile can degrade very significantly when applied to the actual process due to model plant mismatches. In order to address this issue, the optimisation objective function can be augmented by an additional term (or an additional objective in multi-objective optimisation) to penalise wide model prediction confidence bound at the end-point of a batch. By such a means, the calculated optimal control profile is much reliable in the sense that, when being applied to the actual process, the degradation in control performance is limited.

Speech Title: Data-driven Applications for Semiconductor/Display Manufacturing
Abstract: The semiconductor and display manufacturing industries have many different processing steps involved and a variety of sensors techniques are applied to the process tools to gather potential useful information as many as possible. It allows us to imagine that there would be a huge amount of data available. The data-driven approaches including machine learning methodologies are actively being studied and being developed to obtain better product quality monitoring or control methods tackling limitations of the conventional methods such as the univariate sensor monitoring. Now it is applied for many different problems in the manufacturing environment from automatic defect detection to quality prediction. Some examples will be discussed. One of main applications widely applied to the manufacturing site is automated defect detection and classification using deep learning methods. There are several inspection steps during the production process and most of them are carried out manually by human inspection engineers. Many researches demonstrate superior detection performance of DL models. Another application using machine learning techniques is fault detection & diagnosis of the process tool. Process tools normally have number of sensors which are highly correlated and the level of difficulties to monitor every sensor’s behaviors with conventional methods. The machine learning techniques can extract certain patterns that are useful for fault detection and engineers now are able to apply it to their workflows. Machine learning approaches can be beneficial in speed as it can detect faults earlier and faster. However, there is always a limitation we need to overcome and this limitation is how well we can interpret the model’s results. To overcome this, we have to understand the physical background of the process and try to integrate model result with the physics to obtain meaningful solutions.
Bio: Jeong Jin Hong, Ph.D. has been a data science manager at AMAT since 2019 with data-driven model algorithm development using various types of data collected from the tool.
