• A Close-up Look at White-Speck Neps in Cotton
  of environmental concerns. We'd like to see if biodegradable enzymes can do the job and using electron microscopes is one way to find out." Another example of how Goynes' work with SEMs has benefited the environment is his study of nonwoven fabrics. These materials are often used in disposable cloth...
• Infrared Viewer Frequently Asked Questions
  . Infrared viewer FAQs. Answers to frequently asked questions regarding our infrared viewing devices. How does an infrared viewer work?. Power Technology, Inc.'s infrared viewers work by focusing the infrared light reflected by or emitted. from a chosen subject onto the image tube. An electron image...
• New Look At Layered Material Lends Insight To Silicon
  the structure with the electron microscope. After comparing the data to their computer simulations, Windl and Duscher found to their surprise that the interface between the germanium and silicon dioxide was perfect down to the atom -- a condition known as "atomically sharp," which to Windl's knowledge had...
• MICRO: Applying statistical methods to implement dry polymer removal techniques
  involving the HF dip method were performed in a hood from Semiconductor Plastic Modules. A Tencor TF was used to obtain oxide- and poly-layer measurements, while a KLA 8100 CD scanning electron microscope (SEM) from KLA-Tencor (San Jose) provided automatic critical dimension (CD) measurements...
• Smart Computing Article - holography to Honeywell
  of the scanning electron microscope. His technique would have come to fruition earlier if a device that could effectively record an image had been available. That wouldn't happen until two U.S. scientists from the University of Michigan, Emmet Leith and Juris Upatnieks, made the first hologram in 1962...
• Tracking the performance of photolithographic processes with excursion monitoring
  designed resist pattern. The monitor wafer is then inspected, defects are classified, and the resist critical dimension (CD) is measured using scanning electron microscopy (SEM). Defect and measurement data are plotted in tool-specific SPC charts to monitor each tool s performance and identify trends...

• The role of sodium
  and examined under a scanning electron microscope (SEM). Electron dispersive spectroscopy (EDS) was performed on the individual particles to determine their surface composition. A number of dispersing systems (incorporating sodium silicate, soap and calcium in various ratios) were compared at addition...
• Getting Plant Genes To Glow: New technique emerges from metal absorption studies
  and marked with a probe that binds a fluorescent agent or a labeled antibody to the mRNA for a specific gene. This sectioned tissue is usually viewed under an electron microscope to determine which cells within it are labeled. The labeling indicates where the gene is expressed. "This is quite labor...
• A Better Way To Glue Micro-Size Parts For Medical Devices
  , with no leaks, so the device appeared to be sealed successfully inside and outside. With an electron microscope, the researchers saw that most of the HEMA had flowed cleanly throughout the device, but some of it remained behind in the corners of the reservoirs. As a result, the sharp corners were all...
