Book excerpt: Manufacturing variations refer to the uncertainties in the processes and inconsistency in the products produced. There have been increasing efforts to minimize the manufacturing variations, and reducing manufacturing variations in advanced manufacturing processes and systems is becoming more important. Advanced manufacturing processes and systems integrate manufacturing with innovative science and technologies and boost manufacturing efficiency and productivity. The integration with sensor technology now provides massive data, creating unprecedented research opportunities to model and analyze through data-driven models and methods. However, at the same time, advanced manufacturing processes and systems involve new critical challenges in modeling and managing the manufacturing variations. Many advanced manufacturing processes and systems have complex dynamics and transformation and multiple components involved, which create significant variations and uncertainties. However, physics-based models are often unavailable and often fail to address the uncertainties. This dissertation addresses multiple challenges in modeling and managing the manufacturing variations: (1) Variation source identification in multistage manufacturing systems: In multistage manufacturing systems, where multiple operations are performed in a series of stages (e.g., workstations), the variations produced from operations propagate to downstream measurements. In such systems, it is crucial to identify faulty operations with excessive variations among a large number of operations based on the quality measurements. We consider a common case where the measurements are not directly taken from the operations but from products in the downstream stage and the number of operations is much larger than the number of measurements. However, inferring underlying variations of numerous operations by limited measurements cause technical challenges in statistical inference. Therefore, we want to establish a statistical model that can identify faulty operations by leveraging the Engineering domain knowledge. Three types of domain knowledge are considered: a) The fact that faults occur sporadically; b) Practitioners' empirical knowledge of the faults occurrence frequency; c) Various tolerance levels on variations across operations. (2) Modeling inkjet printing manufacturing process: The inkjet printing manufacturing process involves significant random variations due to the complex physical and chemical dynamics of the nanomaterial pieces in the printed ink. Process variations create significant uncertainties in the manufactured product quality, but such uncertainties have not been studied. Therefore, it is crucial to model the randomness in the manufacturing outcome in terms of process parameters. Building upon the statistical model, this work further aims to establish a statistic that evaluates the manufacturing outcome quality, and ultimately identifies abnormal manufacturing outcomes. (3) Statistical calibration of underlying physical variable: In designing manufacturing processes and products, inferring the underlying physical input variable, called statistical calibration, is often needed. For example, by using the GFET nanosensor outputs, inferring the amount of the target substance in the environment is important. Furthermore, the uncertainty of the inferred variable needs to be quantified. However, due to significant process variations in manufacturing, the GFET nanosensor outputs involve significant random variations, and thus precise inferring is challenging. Specifically, random shapes and random locations of functional data need to be modeled for precise calibration. (4) Optimal parameter design through Bayesian optimization: It is very crucial to design manufacturing processes or products so that they have small quality variations while satisfying the overall quality (i.e., robust design). However, data are often costly to acquire especially in the designing stage. Furthermore, the underlying exact relationships between the design variables and the mean and variance of the outputs are not known and are in complex forms. Therefore, a sample efficient data-driven method to find the robust design needs to be established. To address these challenges listed above, four problems are investigated in this dissertation. (i) To build a special sparsity-enhanced Bayesian linear random-effects model to reflect Engineering domain knowledge. With the proposed model, Engineering domain knowledge on sparse faults with excessive variations is incorporated into the model, and the variation sources are successfully identified. (ii) To model the uncertainties in the inkjet printing manufacturing process in terms of physical process parameters. Building upon the proposed model, abnormal manufacturing outcomes are successfully identified. (iii) To establish a non-parametric model to characterize functional data with significant variations. The issue with random shapes and random shifting of functional data is addressed. (iv) To establish sample-efficient stochastic constrained optimization method for constrained robust parameter design. The proposed technique minimizes the variations while satisfying a constraint on the mean of the quality measurements by conducting a small number of experiments. Because the proposed methods are driven by data, these models and methods are very flexible and can be used to address many general problems in other manufacturing processes.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predicting polymeric material behavior during processing and predicting final part properties continues to be a strong research focus within the scientific community as it involves taking into consideration a wide range of time-dependent variables. By use of data-driven modeling, the materials development process can be accelerated, and the highly predictive modeling techniques can facilitate the development of smart manufacturing systems. This dissertation worked on solving polymer engineering problems by use of data-driven modeling techniques. The first strategy was using data-driven modeling to provide a predictive model with statistical insights of the injection molding process to ensure part quality is maximized for a highly viscoelastic material blend. By injection molding highly viscoelastic materials, the probability of part defects is increased, therefore, it was crucial to use advanced computational techniques to understand the nuances of this highly non-linear process and to predict the outcome before creating material waste from faulty trials. The second strategy was in the use of data-driven modeling for reverse engineering purposes, specifically within materials development. By combining experimental characterization and data-driven modeling, algorithms were developed and compared to prove how highly predictive models can be used as reverse engineering toolboxes. This ultimately informed users of the optimal formulation which would reach the specified target material properties. The final strategy explored using data-driven modeling to validate the high influence of viscous heating within the pressure melt removal process, therefore, work was done in implementing a viscous heating system within a fused filament fabrication (FFF) 3D printer to accelerate the 3D printing process. The instrumented FFF 3D printer proved capable of accelerating print speeds and improving mechanical performance of 3D printed parts, working towards solving two of the largest bottlenecks within additive manufacturing: lead times and part quality. Given the unique capabilities of the data-driven modeling, the novel 3D printer was tested and evaluated via data-driven modeling to provide statistical information regarding which processing parameters were the most influential for improving overall performance of the 3D printing system. The results of this work provide a basis for future research endeavors related to combining data-driven modeling and polymer science, such as in optimizing the newly developed viscous heating 3D printer.

Download or read book Variation Modeling Analysis and Control for Multistage Wafer Manufacturing Processes written by Ran Jin and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Geometric quality variables of wafers, such as BOW and WARP, are critical in their applications. A large variation of these quality variables reduces the number of conforming products in the downstream production. Therefore, it is important to reduce the variation by variation modeling, analysis and control for multistage wafer manufacturing processes (MWMPs). First, an intermediate feedforward control strategy is developed to adjust and update the control actions based on the online measurements of intermediate wafer quality measurements. The control performance is evaluated in a MWMP to transform ingots into polished wafers. However, in a complex multistage manufacturing process, the quality variables may have nonlinear relationship with the parameters of the predictors. In this case, piecewise linear regression tree (PLRT) models are used to address nonlinear relationships in MWMP to improve the model prediction performance. The obtained PLRT model is further reconfigured to be complied with the physical layout of the MWMP for feedforward control purposes. The procedure and effectiveness of the proposed method is shown in a case study of a MWMP. Furthermore, as the geometric profiles and quality variables are important quality features for a wafer, fast and accurate measurements of those features are crucial for variation reduction and feedforward control. A sequential measurement strategy is proposed to reduce the number of samples measured in a wafer, yet provide adequate accuracy for the quality feature estimation. A Gaussian process model is used to estimate the true profile of a wafer with improved sensing efficiency. Finally, we study the multistage multimode process monitoring problem. We propose to use PLRTs to inter-relate the variables in a multistage multimode process. A unified charting system is developed. We further study the run length distribution, and optimize the control chart system by considering the modeling uncertainties. Finally, we compare the proposed method with the risk adjustment type of control chart systems based on global regression models, for both simulation study and a wafer manufacturing process.
