- 요약This PhD dissertation explores significant advances in the compensation and calibration of MEMS (Micro-Electro-Mechanical Systems) devices, particularly focusing on the application of high-performance 4H-SiC (silicon carbide) and AlN (aluminum nitride) technology in MEMS resonators and gyroscopes. The research underscores the critical importance of precise timekeeping and navigation, which are foundational to a broad spectrum of technological applications.Upon providing an introduction in Chapter 1 and a comprehensive study and discussion of SiC material properties in Chapter 2, Chapter 3 of the dissertation is dedicated to the comprehensive study of MEMS resonators. The work elucidates the operational principles of MEMS resonators, which rely on the mechanical vibrations of microfabricated structures. A key focus is on the transduction mechanisms that convert mechanical energy into electrical signals and vice versa. Among these, electrostatic transducers for temperature compensation are highlighted for their compatibility with CMOS processes and low power consumption, despite their challenges such as requiring small airgaps for higher efficiency. This chapter establishes the groundwork for understanding the material and structural properties that influence the performance and reliability of MEMS resonators and conventional temperature compensation techniques.In Chapter 4, the dissertation makes a notable contribution by introducing a novel method for achieving thermal stability and temperature compensation in 4H-SiC MEMS resonators through a built-in stress modulation technique. This method utilizes tensile and compressive stresses in a bonded 4H-SiC on insulator substrate with silicon handle layer to achieve a near-zero temperature coefficient of frequency (TCF) for 4H-SiC beam resonators. The research demonstrates that this technique significantly enhances the stability of beam resonators without compromising their reliability, which is crucial for their application in varying environmental conditions. This approach eliminates the need for external power and frequent calibration, offering an efficient solution for temperature compensation. This achievement represents a significant advance in the field of MEMS technology, providing a robust foundation for developing more reliable and thermally stable MEMS devices.In Chapter 5, the dissertation has introduced and validated machine learning (ML) and deep learning (DL) models to enhance the calibration of AlN-on-Si piezoelectric resonant gyroscopes, particularly when operating in ambient air conditions. By leveraging the XGBoost regression model and Multilayer Perceptron (MLP), the project addressed the challenges posed by increased noise levels and the high cost and time requirements of traditional calibration methods. The project involved comprehensive data preprocessing, exploratory data analysis (EDA), and rigorous model tuning to ensure optimal performance. The results demonstrated that both ML and DL models significantly improve the accuracy and reliability of gyroscope calibration compared to traditional methods, with the DL model showing the greatest enhancement. This research not only advances the calibration techniques for MEMS gyroscopes but also paves the way for their broader application in non-vacuum environments, contributing to the field's technological progress and practical utility.In summary, this dissertation provides an exploration of critical advances in MEMS technology, particularly focusing on enhancing temperature compensation and calibration accuracy through innovative material applications and cutting-edge ML and DL techniques. The work presented in Chapters 3, 4, and 5 collectively contributes to the development of highly stable and accurate MEMS resonators and gyroscopes, paving the way for their broader application in various high-stakes and everyday environments.
