2. 1. Integration and Fabrication Techniques for 3D Micro- and Nanodevices

   Author : Andreas C. Fischer; Frank Niklaus; Karl F. Böhringer; KTH; []
   Keywords : Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; chip-level; through silicon via; TSV; packaging; 3D packaging; vacuum packaging; liquid encapsulation; integration; heterogeneous integration; wafer bonding; microactuators; shape memory alloy; SMA; wire bonding; magnetic assembly; self-assembly; 3D; 3D printing; focused ion beam; FIB;

   Abstract : The development of micro and nano-electromechanical systems (MEMS and NEMS) with entirely new or improved functionalities is typically based on novel or improved designs, materials and fabrication methods. However, today’s micro- and nano-fabrication is restrained by manufacturing paradigms that have been established by the integrated circuit (IC) industry over the past few decades. READ MORE

4. 2. Scanning Tunnelling Microscopy and Spectroscopy of Adsorbates on Aluminium and Silicon

   Author : Mikael Johansson; Synkrotronljusfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alkali metals; Scanning tunnelling spectroscopies; Scanning tunnelling microscopy; Photoelectron Spectroscopy; Single crystal surface; Silicon; Surface structure; Aluminium; Silicides; Fullerenes.; Physics; Fysik; Fysicumarkivet A:1997:Johansson;

   Abstract : The main topic of this thesis is the investigation of atomic andmolecular adsorbates on single crystal surfaces of silicon and aluminiumusing the techniques of scanning tunnelling microscopy (STM) andspectroscopy (STS). The emphasis has been to use atomic-resolutionspectroscopy and imaging to determine the relationship between thesurfaces' geometric and electronic structures. READ MORE

5. 3. Characterization of Process-related Defects in Silicon Carbide by Electron Microscopy

   Author : Per O. Å. Persson; Pirouz Pirouz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Silicon carbide (SiC) is a semiconducting material, which provides advantages compared to other available semiconducting materials. Attractive properties of SiC are the wide bandgap (2.2-3.3 eV), high electric breakdown field (3x106 Vcm-1), high thermal conductivity (5 Wcm-1 K-1) and the chemical stabi!ity. READ MORE

6. 4. Risk factors for the development of chronic renal failure : epidemiological studies on the role of analgesic use, occupational exposures and socioeconomic background

   Author : Michael Fored; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Kidney failure; chronic; Analgesics; non-narcotic; Case-control study; Risk factors; Acetaminophen; Paracetamol; Aspirin; Acetylsalicylic acid; Bias epidemiology ; Education; Socioeconomic factors; occupations; Occupational exposure; Solvents; Metals; heavy; Silicon compounds; Dust.;

   Abstract : Chronic renal failure is a severe condition that reduces life expectancy and typically progresses to end-stage renal disease and a need for renal replacement therapy. In a large proportion of cases, chronic renal failure evolves from known renal or systemic diseases, but in some cases the pathogenesis remains unknown. READ MORE

7. 5. CVD and ALD of Group IV- and V-Oxides for Dielectric Applications

   Author : Katarina Forsgren; Steven George; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; CVD; ALD; Dielectric constant; Tantalum oxide; Ta2O5; Zirconium oxide; ZrO2; Hafnium oxide; HfO2; QCM; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Abstract : Due to the constantly decreasing dimensions of electronic devices, the conventional dielectric material in transistors and capacitors, SiO2, has to be replaced by a material with higher dielectric constant. Some of the most promising candidates are tantalum oxide,Ta2O5, zirconium oxide, ZrO2 and hafnium oxide, HfO2. READ MORE
