21. Design and Characterization of RF-LDMOS Transistors and Si-on-SiC Hybrid Substrates
Abstract : With increasing amount of user data and applications in wireless communication technology, demands are growing on performance and fabrication costs. One way to decrease cost is to integrate the building blocks in an RF system where digital blocks and high power amplifiers then are combined on one chip. READ MORE

22. Copper and Silver Metallization for High Temperature Applications
Abstract : High-temperature electrical- and morphological-stability of interconnect is critical for electronic systems based on wide band gap (WBG) semiconductors. In this context, the thermal stability of both Ag and Cu films with Ta and TaN films as diffusion barriers and/or surface-capping layers at high temperatures up to 800 oC is investigated in this thesis.

23. Electrical Characterisation of (Ag,Cu)(In,Ga)Se2 Thin Film Solar Cells To Investigate Stability
Abstract : This licentiate thesis gives a summary of electrical characterisation techniques, detailing their use to investigate and understand stability and meta-stability in thin-film solar cells, with a focus on the chalcopyrite material system. Experimental data is used to illustrate the information that can be extracted with these measurements, highlighting the deeper insights that can be drawn from complementary measurements. READ MORE

24. Metal Gate Technology for Advanced CMOS Devices
Abstract : The development and implementation of a metal gate technology (alloy, compound, or silicide) into metal-oxide-semiconductor field effect transistors (MOSFETs) is necessary to extend the life of planar CMOS devices and enable further downscaling. This thesis examines possible metal gate materials for improving the performance of the gate stack and discusses process integration as well as improved electrical and physical measurement methodologies, tested on capacitor structures and transistors.
