  • Manufacturing Issues of BEOL CMOS-MEMS Devices 

    Valle Fraga, Juan José; Fernández Martínez, Daniel; Gibrat, Olivier; Madrenas Boadas, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2021-06-07)
    Article
    Open Access
    In this paper we present a comprehensive report on the issues found during the manufacturing of high-yield CMOS-MEMS sensors based on vapor-phase hydrogen fluoride (vapor- HF ) oxide etching. During the study we have ...

    Article
    Open Access
    New projects being implemented or planned at CERN, such as the LHC Injectors Upgrade (LIU), the High-Luminosity LHC (HL-LHC) or the Future Circular Collider (FCC), motivate the change of several architectural paradigms in ...
  • A cmos-mems beol 2-axis lorentz-force magnetometer with device-level offset cancellation 

    Sánchez Chiva, José María; Valle Fraga, Juan José; Fernández, Daniel; Madrenas Boadas, Jordi (2020-10-19)
    Article
    Open Access
    Lorentz-force Microelectromechanical Systems (MEMS) magnetometers have been proposed as a replacement for magnetometers currently used in consumer electronics market. Being MEMS devices, they can be manufactured in the ...
  • Self-controlled 4-transistor low-power min-max current selector
