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.

Advanced techniques of micromachining
Šalomoun, Vojtěch ; Prášek, Jan (referee) ; Pekárek, Jan (advisor)
Fabrication of micro-electro-mechanical systems (MEMS) requires advanced level of miniaturization, which is not achievable by technology used in microeletronics. Socalled micromachining covers many unique techniques of material processing to get microstructures with possible dimensions below 1 m. This bachelor’s thesis gives a general introduce to micromachining of MEMS. Its focus is on bulk and surface micromachining by wet and dry etching. The practical part contains design of microstructures, their manufacturing process and creation of computer models in CoventorWare suite.

CAD systems for MEMS design
Lazar, Jaroslav ; Paloušek, David (referee) ; Hartl, Martin (advisor)
This thesis deals with CAD design tools for MEMS. First part describes and defines MEMS and its basic components. This is followed by a description of methods used to manufacture MEMS. The last part deals with particular CAD design tools, their modules and functions. Mentioned systems are then compared, reviewed and appropriate usage for each of them is suggested. Then the importance and advantages of MEMS are disccussed.
