8. Chemical Vapor Depositionof Si and SiGe Films for High-Speed Bipolar Transistors
Sammanfattning : This thesis deals with the main aspects in chemical vapordeposition (CVD) of silicon (Si) and silicon-germanium (Si1-xGex) films for high-speed bipolar transistors.In situdoping of polycrystalline silicon (poly-Si)using phosphine (PH3) and disilane (Si2H6) in a low-pressure CVD reactor was investigated toestablish a poly-Si emitter fabrication process.

9. Bipolar Transistor Parameter Extraction, Modeling and Test Structure Design
Sammanfattning : In this thesis, techniques are presented for determining the model parameter values required by compact bipolar transistor models in circuit simulators. Specifically, extraction of the Early voltages and the transistor series resistances are treated in detail. Extraction of other compact model parameters is also covered. LÄS MER
10. On Reliability of SiC Power Devices in Power Electronics
Sammanfattning : Silicon Carbide (SiC) is a wide-bandgap (WBG) semiconductor materialwhich has several advantages such as higher maximum electric field, lowerON-state resistance, higher switching speeds, and higher maximum allowablejunction operation temperature compared to Silicon (Si).
