    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas C. Fischer; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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
