Development and fabrication of microelectromechanical systems MEMS
Koňařík, Lukáš ; Dostál, Zbyněk (referee) ; Nováček, Zdeněk (advisor)
This bachelor thesis deals with MEMS microelectromechanical systems. In the first part of the thesis the application areas of these systems are described in general together with specific cases. In addition, COMSOL Multiphysics simulations are explained in detail, as well as an enumeration of the physical principles of MEMS system technologies. In the practical part, models of an electrostatic actuator and a thermomechanical actuator are presented. The work depicts the different steps of fabrication from the initial substrate to the final structure. This process includes cutting the samples using a laser dicer, spin coating, optical lithography, depositing a conductive metal layer on an evaporator, lift-off, etching the structure using a deep reactive ion etching technique, hydrofluoric acid etching, and bonding to an electrical circuit. All steps are documented and performed in the shared laboratories of the Central European Institute of Technology CEITEC Nano. Finally, the results of the whole fabrication process are summarized and discussed.
