    • Al-Al Wafer-Level Thermocompression Bonding applied for MEMS 

      Taklo, Maaike M. Visser; Schjølberg-Henriksen, Kari; Malik, Nishant; Poppe, Erik Utne; Moe, Sigurd T.; Finstad, Terje (Chapter, 2017)
      Wafer-level thermocompression bonding (TCB) using aluminum (Al) is presented as a hermetic sealing method for MEMS. The process is a CMOS compatible alternative to TCB using metals like gold (Au) and copper (Cu), which are ...

    • Conductivity of high-temperature annealed silicon direct wafer bonds 

      Schjølberg-Henriksen, Kari; Tvedt, Lars Geir Whist; Gjelstad, Stein Are; Mørk, Christopher; Moe, Sigurd T.; Imenes, Kristin; Poppe, Erik; Wang, Dag Thorstein (Journal article; Peer reviewed, 2015)
      Silicon direct wafer bonding is a process with many application areas. Depending on the application, perfect insulation or negligible resistance is desired across the bonded interface. We have investigated the resistivity ...

    • Cost-effective processing of a piezoresistive MEMS cantilever sensor 

      Clausen, Ingelin; Moe, Sigurd T.; Vogl, Andreas (Chapter, 2011)
      In this paper cost-effective methods for fabrication of a piezoresistive cantilever sensor for industrial use are focused. The intended use of the presented cantilever is a medical application. A closer description of the ...

    • Electrical, Mechanical, and Hermetic Properties of Low-Temperature, Plasma Activated Direct Silicon Bonded Joints 

      Schjølberg-Henriksen, Kari; Malik, Nishant; Gundersen, Elin Vold; Christiansen, Oscar Rincon; Imenes, Kristin; Fournel, Frank; Moe, Sigurd T. (Journal article; Peer reviewed, 2015)
      The electrical, mechanical, and hermeticity properties of low-temperature, plasma activated direct silicon bonds were investigated. On individual dies with a bonding area ranging from 1–4 mm2, the bonded interface was found ...

    • Fabrication of an array of silicon microscales for the monitoring of chemical processes 

      Lacolle, Matthieu Jean P; Johansen, Ib-Rune; Wang, Dag Thorstein; Moe, Sigurd T.; Sagberg, Håkon; Clausen, Sigmund; Karlsson, Arne; Akporiaye, Duncan (Journal article; Peer reviewed, 2012)
      We present the fabrication and demonstration of a two-dimensional array of scales micromachined in silicon. Each scale consists of a platform suspended by a spring. The mass present on the platform of each scale is measured ...

    • Metal Films for MEMS Pressure Sensors: Comparison of Al, Ti, Al-Ti Alloy and Al/Ti Film Stacks 

      Vereshchagina, Elizaveta; Poppe, Erik Utne; Schjølberg-Henriksen, Kari; Wöhrmann, Markus; Moe, Sigurd T. (Chapter, 2018)
      Thermo-mechanical stability of metal structures is one of the key factors affecting accuracy of micro-electromechanical (MEMS) piezoresistive pressure sensors. In this work, we present the measurement results of stress and ...

    • Non-destructive wafer-level bond defect identification by scanning acoustic microscopy 

      Brand, Sebastian; Tismer, Sebastian; Moe, Sigurd T.; Schjølberg-Henriksen, Kari (Journal article; Peer reviewed, 2015)
      Metal-based thermocompression bonding enables the creation of hermetic seals formed at relatively low processing temperatures and occupying a small portion of the device area. In the current study we have investigated the ...
