    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. 3D property rights an analysis of key factors based on international experience

    Detta är en avhandling från Stockholm : KTH

    Författare :Jenny Paulsson; KTH.; [2007]

  5. 5. The Integration of 3D Geodata and BIM Data in 3D City Models and 3D Cadastre

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Jing Sun; KTH.; [2019]
