21. An Electron Microscopy Study on Materials in Electronic Packaging
Sammanfattning : 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. LÄS MER
22. Development of electron microscopy towards nano-structured porous materials : Focus on novel zeolites from layered silicates and chiral mesoporous nanotubes
Sammanfattning : Three novel zeolites (M-IEZ-MWW, IEZ-FER and IEZ-CDO) have been successfully synthesised from the corresponding precursors. Structure characterisation of those materials was conducted by TEM. LÄS MER
23. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires
Sammanfattning : One common goal of sample analysis is to provide structural, compositional, or functional data in order to improve production parameters. One instrument specialized in such structural and compositional analysis with a high spatial resolution is the transmission electron microscope (TEM). LÄS MER
24. Automatic Virus Identification using TEM : Image Segmentation and Texture Analysis
Sammanfattning : Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s. The technique has been vital for the discovery of new viruses and in establishing the virus taxonomy. Today, electron microscopy is an important technique in clinical diagnostics. LÄS MER
25. High-resolution characterization of TiN diffusion barrier layers
Sammanfattning : Titanium nitride (TiN) films are widely applied as diffusion barrier layers in microelectronic devices. The continued miniaturization of such devices not only poses new challenges to material systems design, but also puts high demands on characterization techniques. LÄS MER
