  2. 11. Fabrication of Electroacoustic Devices for Integrated Applications

    Author : Johannes Enlund; Ilia Katardjiev; Jörgen Olsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik; Elektronik; Electronics;

    Abstract : Electroacoustic technology has in many ways revolutionised the wireless telecommunication industry. The IC compatible fabrication technique of thin film electroacoustic devices has so far provided a considerable increase in device performance and reduction in size. At the moment, new areas where this technology can be of use is under investigation. READ MORE

  4. 12. Advanced TCAD Simulations and Characterization of Semiconductor Devices

    Author : Tony Ewert; Jörgen Olsson; Marcel Pelgrom; Uppsala universitet; []
    Keywords : Electronics; MOSFET; RDF; random dopant fluctuation; asymmetric; parametric mismatch; TCAD; compact modeling; fluctuation model; Elektronik;

    Abstract : Today, micro- and nano-electronic devices are becoming more complex and advanced as the dimensions are shrinking. It is therefore a very challenging task to develop new device technologies with performance that can be predicted. READ MORE

  5. 13. Chemical Mechanical Polishing of Silicon and Silicon Dioxide in Front End Processing

    Author : Markus Forsberg; Jörgen Olsson; Jyrki Molarius; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; chemical mechanical polishing; chemical mechanical planarization; silicon; silicon dioxide; front end; shallow trench isolation; deep trench isolation; bipolar transistor; BiCMOS; wafer bonding; Elektronik; Electronics; Elektronik;

    Abstract : Chemical mechanical polishing (CMP) has been used for a long time in the manufacturing of prime silicon wafers for the IC industry. Lately, other substrates, such as silicon-on-insulator has become in use which requires a greater control of the silicon CMP process. READ MORE

  6. 14. Modeling and electrical characterization of Cu(In,Ga)Se2 and Cu2ZnSnS4 solar cells

    Author : Christopher Frisk; Charlotte Platzer-Björkman; Jörgen Olsson; Janez Krč; Uppsala universitet; []
    Keywords : ;

    Abstract : In this thesis, modeling and electrical characterization have been performed on Cu(In,Ga)Se2 (CIGS) and Cu2ZnSnS4 (CZTS) thin film solar cells, with the aim to investigate potential improvements to power conversion efficiency for respective technology. The modeling was primarily done in SCAPS, and current-voltage (J-V), quantum efficiency (QE) and capacitance-voltage (C-V) were the primary characterization methods. READ MORE

  7. 15. Effect of shear cutting on metal fatigue

    Author : David Gustafsson; Erik Olsson; Jörgen Kajberg; Pär Jonsén; Henrik Sieurin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Punching; Trimming; Shear cutting; Fatigue; HCF; Residual stresses; Hållfasthetslära; Solid Mechanics;

    Abstract : Lightweighting of automotive and heavy-duty vehicle components is an important task that does not need any further motivation or background. It can be read in a large part of the technical papers in the field. A common approach for finding lighter solutions is to increase the material grade while decreasing the material thickness.
