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.

The silicon etching technology
Krátký, Stanislav ; Ježek,, Jan (referee) ; Matějka, Milan (advisor)
This thesis deals with the silicon etching technology. It Examines using of water solution of potassium hydroxide. It focuses on plasma etching of silicon using mixture of CF4 and O2 as the dry way of etching. Important parameters of etching like etching rate of silicon and masking materials, etching selectivity, surface roughness and underetching of mask are determined for both ways. Some additional processes has been examined as well, namely creating of mask of resist and silicon dioxide, lithography process and etching of resist using oxygen plasma.

The impact of quantitative easing on public sector bond yields of selected countries since 2007
Nacházel, Jan ; Jílek, Josef (advisor) ; Pekárek, Štěpán (referee)
This thesis deals with the impact of quantitative easing on public sector bond yields of selected countries in the world. It mentions channels of standard monetary policy tools and channels of quantitative easing, which can be included among unconventional monetary policy tools. This thesis analyses the impacts of quantitative easing, which was done by the Federal Reserve System, the Bank of England and the European Central Bank. Firstly, all these institutions fought against the financial crisis with standard monetary policy tools. However, those tools were not very effective, therefore the institutions moved to non-standard tools. After the analysis based on event-study method was carried out, it was found out that mainly the first announcements about the policy of quantitative easing were always the most effective in decreasing government bond yield. The subsequent expansion of the policy of quantitative easing did not have such impact. The main benefit of this thesis is in the examination of the impact of later statements regarding quantitative easing on government bond yield, which were not effective in decreasing government bond yield.
