scanning electron microscope (ESEM). Recent developments in ESEM have enabled in-situ study of liquid/solid interactions within the microscope chamber 5-8 . The most important benefit of the ESEM over other types of microscopy is the fact that dynamic solid-liquid interactions can be ob-served in real time at high magnifications 5 .

It revealed that the existence of oxygen is an important factor leading to the deterioration of ta-C. Besides the cross-section observation shows that there two kinds of defects in the coating. These two kinds of defects show

particle characteristics. We focused our ESEM measurements on individual particles which were not in contact with any others. High-resolution images of submicron particles were obtained by introducing and controlling the amount of water vapor in the Electro Scan Model E-3 ESEM equipped with a temperature- controlled sample stage.

Hybrid Microassembly in Environmental Scanning Electron

The introduction of environmental scanning electron microscope (ESEM) has alleviated the requirement of high vacuum imaging conditions of the conventional SEM. The ESEM allows pressures high enough for liquid water in the specimen chamber by introducing a variable pressure aperture and specialized gaseous secondary electron detector 6

To optimize very high magnification imaging the stigmator can be adjusted by holding the Shift key and the right mouse button simultaneously.

Environmental Scanning Electron Microscopy (ESEM) XOS

Environmental scanning electron microscopy (ESEM) is a unique system in which uncoated biological and industrial materials can be examined with an electron beam in a high chamber pressure atmosphere of water vapor. Therefore specimens can be analyzed using ESEM without destruction and additional specimen preparation procedures.
