  2. 1. Materials design and characterization of the active regions of gas sensitive field-effect devices

    Author : Anna Elisabeth Åbom; Udo Weimar; Linköpings universitet; []
    Keywords : ;

    Abstract : Metal-Insulator-Semiconductor (MIS) field-effect devices with catalytic metal layers are sensitive to several important gases, such as hydrogen, ammonia, hydrocarbons and alcohols. The gas sensitivity and selectivity depends on the properties of the active regions of the device. READ MORE

  4. 2. Investigation of Novel Metal Gate and High-κ Dielectric Materials for CMOS Technologies

    Author : Jörgen Westlinder; Jörgen Olsson; Stefan Bengtsson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; metal gate; high-κ dielectics; titanium nitride; zirconium nitride; MOSFET; thin film; tantalum oxide; aluminum nitride; Elektronik; Electronics; Elektronik;

    Abstract : The demands for faster, smaller, and less expensive electronic equipments are basically the driving forces for improving the speed and increasing the packing density of microelectronic components. Down-scaling of the devices is the principal method to realize these requests. READ MORE

  5. 3. Tunnel Emitter Transistors

    Author : Erik Aderstedt; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TET; tunneling; siO2< sub>; tunnel emitter transistor; MOS; Ta2< sub>O5< sub>; silicon; high- #954; BICFET; dielectrics;

    Abstract : The Tunnel Emitter Transistor is based on the modulation of the tunnel current in a Metal Oxide Semiconductor (MOS) structure with an ultra-thin oxide layer. The modulation is accomplished by injecting charge to the oxide-semiconductor interface from a third terminal. READ MORE

    Abstract : This thesis is concerned with an investigation of the microstructure on materials in electronic packaging. The materials include Ag-filled conductive adhesives, Sn-Ag-based lead free solders and metal-oxide semiconductors. READ MORE

  7. 5. Fundamental Processes in SiO2 under Ion Bombardment

    Author : Harald Jacobsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Investigations of sputtering, electron emission and oxide growth under 40-300 keV H+, He+, N+, Ne+, Ar+, Kr+ and Xe+ ion bombardment of SiO2 are presented in this thesis. To accurately determine SiO2 sputtering yields, a new measurement method was developed where the electron emission was monitored during sputtering through thin SiO2 films on Si substrates. READ MORE
