Transmission electron microscope
What it is
How it works
General reference — not yet source-verifiedTransmission electron microscopes pass a beam of electrons through an ultrathin specimen, interacting with the sample as the beam passes through it.
Where it fits in the process flow
General reference — not yet source-verifiedTransmission electron microscopes are used in metrology and inspection applications where high-resolution imaging of internal structures is required.
In a semiconductor or materials fabrication context, transmission electron microscopes are typically used for off-line analysis and characterization of samples rather than for inline process control.
Applications
General reference — not yet source-verifiedThe JEM-1 is applied to the examination of materials at the microstructural and nanoscale level, including the observation of crystalline arrangement and defects.
Transmission electron microscopes of this class are used in failure analysis, materials science research, and the characterization of thin films and interfaces.
