2. 1. The Buried Oxide of Silicon on Insulator Materials

   Author : Per Ericsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxide defects; internal oxidation; aluminum oxide; wafer bonding; SOI; silicon on insulator; buried oxide;

   Abstract : The buried oxide of silicon on insulator (SOI) wafers plays an important role in the operation of electronic devices made on such materials. The presence of defects in the buried oxide can seriously degrade the performance of a circuit. READ MORE

4. 2. Electric Charges on Insulator Surfaces and their Influence on Insulator Performance

   Author : Hans Sjöstedt; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EPDM; silicone rubber; material properties; surface potential measurements; outdoor insulation materials;

   Abstract : AbstractPolymeric materials used in high voltage insulation systems are subjected to electric fields which can be strong enough to initiate electrical discharges in the surrounding gas environment. Generated electrical charges may be deposited on polymer surfaces and alter electric field distributions, thus affecting insulation performance and their corresponding breakdown characteristics.

5. 3. Submillimeter-Wave Waveguide Frontends by Silicon-on-Insulator Micromachining

   Author : Adrian Gomez-Torrent; Joachim Oberhammer; Umer Shah; Goutam Chattopadhyay; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; antenna; orthomode transducer; switch; waveguide; radiofrequency; beamforming network; submillimeter-wave; terahertz; silicon micromachining; deep reactive ion etching; silicon on insulator; Electrical Engineering; Elektro- och systemteknik;

   Abstract : This thesis presents novel radiofrequency (RF) frontend components in the submillimeter-wave (sub-mmW) range implemented by silicon micromachining, or deep reactive ion etching (DRIE). DRIE is rapidly becoming a driving technology for the fabrication of waveguide components and systems when approaching the terahertz (THz) frequency range. READ MORE

7. 5. Fabrication of Group IV Semiconductors on Insulator for Monolithic 3D Integration

   Author : Ali Asadollahi; Mikael Östling; Paul R. Berger; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic three dimensional M3D integration; strained germanium on insulator sGeOI pMOSFETs; silicon silicon-germanium on insulator sSOI sSiGeOI nMOSFETs; Si0.5Ge0.5 strain-relaxed buffer SRB ; direct bonding; chemical mechanical polishing CMP ; compressively strained GeOI; tensile strained Si0.5Ge0.5OI;

   Abstract : The conventional 2D geometrical scaling of transistors is now facing many challenges in order to continue the performance enhancement while decreasing power consumption. The decrease in the device power consumption is related to the scaling of the power supply voltage (Vdd) and interconnects wiring length. READ MORE
