  2. 21. An Electron Microscopy Study on Materials in Electronic Packaging

    Author : Lilei Ye; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MOS; conductive adhesives; Cu7Sn6; microstructure; SEM; lead-free solders; TEM; crystal structure; Cu6Sn5; modulation structure;

    Abstract : 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. READ MORE

  4. 22. Development of electron microscopy towards nano-structured porous materials : Focus on novel zeolites from layered silicates and chiral mesoporous nanotubes

    Author : Juanfang Ruan; Osamu Terasaki; James C. Vartuli; Stockholms universitet; []
    Keywords : Transmission electron microscopy; Layered silicates; Chiral mesoporous nanotubes; strukturkemi; Structural Chemistry;

    Abstract : 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. READ MORE

  5. 23. Nanoscale electron tomography and compositional analysis of Aerotaxy nanowires

    Author : Axel Persson; -lup-obsolete; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission Electron Microscopy; Electron tomography; Nanowires; Aerotaxy;

    Abstract : 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). READ MORE

  6. 24. Automatic Virus Identification using TEM : Image Segmentation and Texture Analysis

    Author : Gustaf Kylberg; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : 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. READ MORE

  7. 25. High-resolution characterization of TiN diffusion barrier layers

    Author : Marlene Mühlbacher; Lars Hultman; Christian Mitterer; Lars Johnson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; TiN; Microstructure; Transmission electron microscopy; TEM; Atom probe tomography; APT;

    Abstract : 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. READ MORE
