Download or read book Poly SiGe for MEMS above CMOS Sensors written by Pilar Gonzalez Ruiz and published by Springer Science & Business Media. This book was released on 2013-07-17 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polycrystalline SiGe has emerged as a promising MEMS (Microelectromechanical Systems) structural material since it provides the desired mechanical properties at lower temperatures compared to poly-Si, allowing the direct post-processing on top of CMOS. This CMOS-MEMS monolithic integration can lead to more compact MEMS with improved performance. The potential of poly-SiGe for MEMS above-aluminum-backend CMOS integration has already been demonstrated. However, aggressive interconnect scaling has led to the replacement of the traditional aluminum metallization by copper (Cu) metallization, due to its lower resistivity and improved reliability. Poly-SiGe for MEMS-above-CMOS sensors demonstrates the compatibility of poly-SiGe with post-processing above the advanced CMOS technology nodes through the successful fabrication of an integrated poly-SiGe piezoresistive pressure sensor, directly fabricated above 0.13 m Cu-backend CMOS. Furthermore, this book presents the first detailed investigation on the influence of deposition conditions, germanium content and doping concentration on the electrical and piezoresistive properties of boron-doped poly-SiGe. The development of a CMOS-compatible process flow, with special attention to the sealing method, is also described. Piezoresistive pressure sensors with different areas and piezoresistor designs were fabricated and tested. Together with the piezoresistive pressure sensors, also functional capacitive pressure sensors were successfully fabricated on the same wafer, proving the versatility of poly-SiGe for MEMS sensor applications. Finally, a detailed analysis of the MEMS processing impact on the underlying CMOS circuit is also presented.

Download or read book Fabrication and Characterization of Thin Film Pressure Sensors Using Novel Materials written by Victor Samoei and published by . This book was released on 2020 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thin-film pressure sensors have received widespread attention in recent times due to its ease of manufacture, characterization, and fatigue strength. Commercial fabrication of these sensors is inexpensive and compatible with the current manufacturing technologies. It has been found that the sensitivity of the flexible pressure sensor depends on the sensing pressure, the microstructural dispersion of nanoparticles, and the compatibility of the binder and the nanoparticles. The binder/particle dispersion should be such that it facilitates the formation of a greater number of conduction paths with a slight change in sensing pressure. The objective of this thesis includes the fabrication and characterization of a thin-film pressure sensor using different novel materials. The first material to be investigated was ZnO. ZnO thin-film materials that have received a great deal of attention due to its unique properties of being a semiconductor with wide bandgap and piezoelectric effect. The sensor characteristic of ZnO was compared with barium-titanate (BaTiO3) Gallium arsenic (GaAs) and Polyvinylidene fluoride (PVDF). The second material to be investigated was aluminum-doped zinc oxide (AZO). AZO has attracted a great deal of attention in many applications because of its nontoxicity, abundancy, and lower cost than other materials such as indium tin oxide (ITO). The AZO films were deposited on polyethylene (PE) substrates by a radiofrequency (rf) magnetron sputtering method. The piezoresistive sensor was tested for different pressures in vacuum and gage pressure conditions. The response characteristics indicated that resistance increased with the bending of the AZO layer in both compressive and tensile operation modes. The sensor characteristics exhibited that the AZO piezoresistive sensor can be used to measure ambient pressure quantitatively. This investigation indicated that AZO can be used as an alternative material for the fabrication of pressure sensors. Lastly, the materials that were investigated are carbon black/ Poly (vinylidene fluoride) (CB/PVDF), graphene/PMMA, and graphene/PVDF composites. The conductive CB/PVDF material was prepared by the wet-cast method and deposited into a flexible polyethylene (PE) substrate, while the graphene composites were prepared by the solvent cast method. The surface morphology, crystal structure, and material properties were studied using SEM and X-ray diffraction methods. Sensitivity, response time, and recovery time were analyzed by testing the sample in the deferent pressure range and vibration modes. The repeatability and reproducibility characteristics of the sensor were studied and found that the sensor exhibits excellent characteristics. The sensors were subjected to different loading/unloading pressures. The resistance of the sensor remained stable indicating that the sensor had a high degree of reproducibility.

Available in PDF, EPUB and Kindle. Book excerpt: Micro-ElectroMechanical Systems is an inter-disciplinary technology field that has seen considerable growth over the years. It utilizes conventional semiconductor fabrication process flow as well as novel micro-fabrication techniques to create highly integrated ElectroMechanical systems such as sensors, actuators, switches, pumps and other devices with a wide range of industrial applications. By providing the capability of creating System-On-A-Chip, MEMS technology offers the prospect of highly sophisticated and integrated systems that are very low cost. The purpose of this project is to design, fabricate, and test a MEMS based, passive pressure sensor as a proof of concept targeted at possible remote sensing applications. For the targeted applications, purely passive sensor is a better alternative to sensors involving active circuitry, since it removes much of the design complexities from the sensor, and no battery is needed. Information such as technology selection, analysis of the sensor's response to pressure, and detailed fabrication process flow will be presented. Results from laboratory testing will also be presented.
