Pre-Meeting Topical Conference

2002 ◽  
Vol 8 (I1) ◽  
pp. 20-20

Topic: Characterization of Non-Conductive or Charging Materials by Microbeam AnalysisThe goal of this topical conference is to present the state of the art for materials characterization of non-conductive or charging materials using microbeam analysis. Examples of charging materials include polymeric materials, ceramic materials, and photoresist materials in the microelectronic industry. Also, the characterization of biological specimens will be covered because they are prone to problems related to charging. These materials are of great technological importance and their characterization is still a great challenge because they charge when analyzed with an electron beam. The techniques of microbeam analysis that will be considered are: X-ray Microanalysis in the Electron Microprobe, Low Voltage Scanning Electron Microscopy, Environmental Scanning Electron Microscopy, Analytical Electron Microscopy with Field Emission Transmission Electron Microscopy, and Focused Ion Beam Milling for specimen preparation. World experts will present papers on these topics. Papers from this topical conference will be published in a special issue of Microscopy & Microanalysis.

The morphological characterization of any polymer blend plays an important part in the development of a new blend system because the properties of blends are dictated by phase morphology which is dependent upon the chemistry and the processing conditions. Light microscopy, scanning electron microscopy and transmission electron microscopy are the most commonly used microscopical techniques for morphological characterization. Transmission electron microscopy techniques provide the best resolution (≈ 0.3 nm) but are limited in the size of sample area and require elaborate sample preparation procedures. Surface charging and beam damage problems have been some of the drawbacks of conventional scanning electron microscopy with non-conducting materials like polymers.The use of low accelerating voltage scanning electron microscopy (LVSEM) in the characterization of polymers and other non-conducting materials is beginning to be recognized.

There has been an increase in awareness in low voltage scanning electron microscopy (LVSEM) of polymers in recent years because not only is it possible to use uncoated or very lightly coated (1-5nm) polymer samples but also due to an inherent advantage of limited beam damage of polymer samples by low energy beams. A steady increase in the use of low accelerating voltages for characterizing polymers has been made possible due to some major developments, such as high brightness field emission source, better lens and column design to minimize lens aberrations, and newer and improved detector systems with higher collection efficiency, incorporated by instrument manufacturers in their newer commercial models in recent years. Although there is still room for further improvements, the described instrumental changes have made possible the appreciation of LVSEM in characterization of polymers and non-conducting, beam sensitive materials.
