1. Chemical Mechanical Polishing of Silicon and Silicon Dioxide in Front End Processing
Abstract : Chemical mechanical polishing (CMP) has been used for a long time in the manufacturing of prime silicon wafers for the IC industry. Lately, other substrates, such as silicon-on-insulator has become in use which requires a greater control of the silicon CMP process. READ MORE

2. Silicon Germanium heterojunction bipolar transistors : Large-signal modeling and low-frequency noise characterization aspects
Abstract : 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. READ MORE

3. Process Design Kit and High-Temperature Digital ASICs in Silicon Carbide
Abstract : Electronics such as microprocessors are highly demanded to monitor or control a process or operation in temperature critical (300 ºC to 600 °C) applications. State-of-the-art silicon-based integrated circuits (ICs) have been improved significantly throughout the years but mainly for a low-temperature ambient. READ MORE

4. Processing and characterization of GaN/SiC heterojunctions and SiC bipolar transistors
Abstract : Silicon Carbide (SiC) and Gallium Nitride (GaN) are bothwide bandgap semiconductors that have been suggested for highpower, high voltage, and high temperature applications. Themost investigated SiC devices so far are the Schottky diode,PiN diode and the field effect transistor. READ MORE

5. SiGeC Heterojunction Bipolar Transistors
Abstract : Heterojunction bipolar transistors (HBT) based on SiGeC havebeen investigated. Two high-frequency architectures have beendesigned, fabricated and characterized. Different collectordesigns were applied either by using selective epitaxial growthdoped with phosphorous or by non-selective epitaxial growthdoped with arsenic. READ MORE
