    Abstract : Direct semiconductor wafer bonding has emerged as a technology to meet the demand foradditional flexibility in materials integration. The applications are found in microelectronics, optoelectronics and micromechanics. For instance, wafer bonding is used to produce silicon-on-insulator (SOI) wafers. READ MORE

  6. 4. The RDGT - Integration of Micromechanics and Electronics by Plasma Assisted Wafer Bonding

    Author : Anke Sanz-Velasco; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bonding; displacement measurement; oxygen plasma; low temperature wafer bonding; capacitive detection; high resolution; CMOS compatibility; MOSFET; low impedance sensing; resonant gate transistor;

    Abstract : A high-resolution capacitive sensing technique is presented in this thesis: the Resonant Double Gate Transistor (RDGT). The major advantage of the RDGT compared to "pure" capacitive sensing techniques is its low output impedance because of the direct capacitance to current conversion of the transistor. READ MORE

  7. 5. Loss and recovery of hydrophobicity of polydimethylsiloxane after exposure to electrical discharges

    Author : Henrik Hillborg; KTH; []
    Keywords : silicone rubber; polydimethysiloxane; dydrophobicity; corona; air-plasma; oxygen-plasma; surface characterisation;

    Abstract : Silicone rubber based on polydimethylsiloxane is used ashigh voltage outdoor insulation, due to its ability to preservethe hydrophobic surface properties during service and evenregain hydrophobicity after exposure to electrical discharges.The underlying processes for the hydrophobic recovery arediffusion of low molar mass siloxanes from the bulk to thesurface and reorientation by conformational changes ofmolecules in the surface region.
