This thesis outlines the principles, device physics, and technological applications of electronics based on the ultra-wide bandgap semiconductor aluminum nitride. It discusses the basic principles of electrostatics and transport properties of polarization-induced two-dimensional electron and hole channels in semiconductor heterostructures based on aluminum nitride. It explains the discovery of high-density two-dimensional hole gases in undoped heterojunctions, and shows how these high conductivity n- and p-type channels are used for high performance nFETs and pFETs, along with wide bandgap RF, mm-wave, and CMOS applications. The thesis goes on to discuss how the several material advantages of aluminum nitride, such as its high thermal conductivity and piezoelectric coefficient, enable not just high performance of transistors, but also monolithic integration of passive elements such as high frequency filters, enabling a new form factor for integrated RF electronics.

The design and fabrication of MEMS Inertial Sensors (both accelerometers and gyroscopes) made of Aluminum Nitride (AlN) is described in this dissertation. The goal of this work is to design and fabricate inertial sensors based on c-axis oriented AlN polycrystalline thin films. AlN is a post-CMOS compatible piezoelectric material widely used for acoustic resonators, such Bulk Acoustic Wave (BAW) and Lamb Wave Resonators (LWR). In this work we develop the design techniques necessary to obtain inertial sensors with AlN thin film technology. Being able to use AlN as structural material for both acoustic wave resonator and sensing elements is key to achieve the three level integration of RF-MEMS components, sensing elements and CMOS in the same chip. Using AlN as integration platform is particularly suitable for large consumer emerging markets where production costs are the major factor that determine a product success. In order to achieve a platform integration, the first part of this work focuses on the fabrication process: starting from the fabrication technology used for LWR devices, this work shows that by slightly modifying some of the fabrication steps it is possible to obtain MEMS accelerometers and gyroscopes with the same structural layers used for LWR. In the second part of this work, an extensive analysis, performed with analytical and Finite Element Models (FEM), is developed for beam and ring based structures. These models are of great importance as they provide tools to understand the physics of lateral piezoelectric beam actuation and the major limitations of this technology. Based on the models developed for beam based resonators, we propose two designs for Double Ended Tuning Fork (DETF) based accelerometers. In the last part of the dissertation, we show the experimental results and the measurements performed on actual devices. As this work shows analytically and experimentally, there are some fundamental constraints that limit the ultimate sensitivity of piezoelectric sensors based on resonating beam structures. Although the limitations of the structures here considered cannot achieve tactical grade sensitivities, this research proves that it is possible to achieve performances close to those required by large consumer electronics. This work proves that AlN based platforms can be a great opportunity for future developments in IMU and in general for MEMS integrated solutions.

A novel metallization for aluminum nitride substrates to package silicon carbide integrated circuits for use at temperatures of 600 deg C and above was investigated. Chemical equilibrium calculations were used to determine the chemical compatibility of several refractory and transition metal disilicides with AlN and SiC. Tungsten disilicide, niobium disilicide, and titanium disilicide were selected for diffusion couple and thin film deposition studies. AlN-WSi2-SiC, AlN-NbSi2-SiC, and AlN-TiSi2-SiC diffusion couples were formed at 1000 deg C and 1200 deg C. WSi2, NbSi2, and TiSi2 thin films were deposited by RF sputtering on AIN substrates and heat treated at 900 deg C, 1000 deg C, and l200 deg C in an argon atmosphere, while WSi2 thin film was deposited on a single crystal SiC wafer and heat treated at 900 deg C. Sheet resistivities were measured, and interfaces were characterized by scanning and transmission electron microscopy imaging, electron diffraction, and energy dispersive x ray microanalysis spectroscopy. The results show that metal silicides appear to be promising as metallization for aluminum nitride for use at 600 deg C and above.

Abstract: Over the past several decades, the technology of micro-electromechanical system (MEMS) has advanced. A clear need of miniaturization and integration of electronics components has had new solutions for the next generation of wireless communications. The aluminum nitride (AlN) MEMS contour-mode resonator (CMR) has emerged and become promising and competitive due to the advantages of the small size, high quality factor and frequency, low resistance, compatibility with integrated circuit (IC) technology, and the ability of integrating multi-frequency devices on a single chip. In this article, a comprehensive review of AlN MEMS CMR technology will be presented, including its basic working principle, main structures, fabrication processes, and methods of performance optimization. Among these, the deposition and etching process of the AlN film will be specially emphasized and recent advances in various performance optimization methods of the CMR will be given through specific examples which are mainly focused on temperature compensation and reducing anchor losses. This review will conclude with an assessment of the challenges and future trends of the CMR.

Microelectromechanical systems (MEMS) sensors using ultrathin aluminum nitride (AlN) film were developed and fabricated using conventional photolithography techniques in the class 100 clean room with a view to integrate them in flexible substrates along with flexible electronics. The MEMS sensors were designed, analytically modeled, fabricated and characterized. Some of the MEMS sensors were only designed and simulated using finite element method (FEM) for the scope of the dissertation. These MEMS sensors can be applied to many applications such as automobile, robotics, biomedical, biometrics, health condition monitoring, GPS tracking devices, smartphones and aircrafts. MEMS pressure sensors using AlN based piezoelectric film were designed, fabricated and characterized in the form of array of cantilever based structures. A 300 nm thick ultrathin and flexible AlN film with a feature size of ~12 [micron] which was deposited using DC reactive magnetron sputtering system and sandwiched between two electrodes to induce cantilever shaped structures acted as the sensing element of the cantilever sensors. After fabrication, several cantilevers were chosen for electrical characterization. The pressure sensors were characterized in a probe station system to measure the piezoelectric voltage signals and power spectral densities. With the help of simulation results, numerical modeling was also carried out to find the theoretical output voltage ranges and sensitivity of the cantilevers. The simple and flexible cantilevers form the basis for future piezoelectric energy harvesters, pressure sensors, fingerprint sensors and accelerometers using ultrathin AlN film those can be integrated on a system-on-chip (SoC) circuit. Initially, the ultrathin AlN films were developed by changing the deposition temperature and Ar/N2 gas flow ratio and characterized using SEM, XRD and EDX to analyze the quality of the film. Stress analyses were taken into consideration to check the mechanical strength and reliability of the pressure sensors. In addition, bending performance was also analyzed by calculating the radius of curvature (ROC) of the cantilevers. Finally, noise performance was also analyzed. Ultra-thin AlN based novel flexible MEMS fingerprint sensors were designed using finite element method i.e., CoventorWare® with a view to improve the pixel resolution and, hence, the quality of scanned fingerprint image. Two different sized pixel dimensions were used for the design of three fingerprint sensors; they are: a) FPS725A b) FPS725B, and c) FPS1016. The pixel dimension for FPS725A and FPS725B was 35 [micron] by 35 [micron]. The pixel feature was equivalent to an imaging resolution of 725 dot-perinch (dpi). The other sensor had a pixel size of 25 [micron] by 25 [micron] and was equivalent to an imaging resolution of 1016 dpi. In both type of sensors, 200 nm thick, ultrathin AlN film was used as the sensing element. The difference between FPS725A and FPS725B was the location of the sensing element. In FPS725A, AlN film was deposited on top of Al2O3 diaphragm while in FPS725B, AlN was located inside the diaphragm. The fabrications process flow will be discussed in details in the fingerprint sensor chapter. In brief, the fingerprint sensors were comprised of array of pixels and each pixel was made of a cavity like structure which was basically an aluminum oxide (Al2O3) based structure. Underneath the cavity like structure, there was an adjacent piezoelectric plate or film which was sandwiched between two metal electrodes. The total area of the sensors is identical and considered to be 15 mm by 15 mm for practical use. Piezoelectric output voltage with respect to various applied finger pressure were calculated using the stress contour found from the simulation results. Finally, piezoelectric response for each sensor for different finger pressure was found from the slope of the piezoelectric voltage versus applied force plot. The average piezoelectric responses are found to be 225.74 V/N, 115.58 V/N, and 125.52 V/N for FPS725A, FPS725B, and FPS1016, respectively. Stress analysis and noise performance of the sensors were studied. For practical use, the CMOS readouts will be taken from the Silicon substrate through the electrical metallization of pure metal electrodes which will be covered in the chapter. An AlN based piezoelectric z-axis MEMS accelerometer was designed and simulated using CoventorWare®. Modal harmonic analysis was carried out and the simulated resonant frequency was found to be 2.26 kHz. Various loads were applied on top proof mass of the accelerometer ranging from 1g to 10g. Piezoelectric output voltages due to applied loads were calculated. The voltages ranged from 0.00082 V to 0.000082 V. The piezoelectric response or sensitivity was also calculated and found to be 0.000082 V/N. Noise performances was also analyzed and noise equivalent acceleration (NEA) was calculated. Noise equivalent acceleration was found to be 0.253 g/[square root]Hz.
