1. Ge/high-k Gates for Monolithic 3D Integration
Sammanfattning : Continuous scaling of transistor dimensions has been in the heart of semiconductorindustry for many years. Recently the scaling has been enabled by various performance boosters which resulted in increased processing complexity and cost, forcing the chip manufacturers to look for some alternative solutions.

2. Germanium layer transfer and device fabrication for monolithic 3D integration
Sammanfattning : Monolithic three-dimensional (M3D) integration, it has been proposed,can overcome the limitations of further circuits’ performance improvementand functionality expansion. The emergence of the internet of things (IoT) isdriving the semiconductor industry toward the fabrication of higher-performancecircuits with diverse functionality. LÄS MER
3. Silicon Germanium heterojunction bipolar transistors : Large-signal modeling and low-frequency noise characterization aspects
Sammanfattning : In this thesis, aspects of the Silicon Germanium (SiGe) Heterojunction Bipolar Transistor (HBT) are addressed. A physics-based electrical large-signal model including thermal dependence has been developed and is implemented using a commercially available simulator package. LÄS MER
4. Applications of Si1-xGex alloys for Ge devices and monolithic 3D integration
Sammanfattning : As the semiconductor industry moves beyond the 10 nm node, power consumption constraints and reduction of the negative impact of parasitic elements become important. Silicon germanium (Si1−xGex) alloys have been used to amplify the performance of Si based devices and integrated circuits (ICs) for decades. LÄS MER
5. Novel Possibilities for Advanced Molecular Structure Design for Polymers and Networks
Sammanfattning : Synthetic and degradable polymers are an attractive choicein many areas, since it is possible to control the way in whichthey are manufactured; more specifically, pathways tomanipulate the architecture, the mechanical properties and thedegradation times have been identified. In this work,L-lactide, 1,5-dioxepan-2-one and ε-caprolactone were usedas monomers to synthesize polymers with different architecturesby ring-opening polymerization. LÄS MER
