    Sammanfattning : Flip chip has since decades been the primary choice for chip interconnect for high performance circuits. Over the last few years, interest from the microwave arena has increased, and at this point in time microwave flip chip is a possible option for volume production. LÄS MER

  3. 3. Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor

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

    Författare :Mikael Antelius; KTH.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microelectromechanical systems; MEMS; Nanoelectromechanical systems; NEMS; silicon; wafer-level; packaging; vacuum packaging; liquid encapsulation; integration; wire bonding; grating coupler; waveguide; Fabry-Perot resonator;

    Sammanfattning : This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. LÄS MER
