... for 300 K (green curve). It is clear from this curve, that very little energy is emitted at wavelengths less than about 3 µm and most of the energy is emitted at wavelengths greater than 5 µm. In order to collect the infrared radiation information from objects near room temperature, a detector sensitive...

...-point IV curves allow the user to determine if a continuity fail is open, resistive, or non-linear. An open will suggest the fail may need Time Domain Reflectometry, (TDR), capacitance, or Magnetic Field Imaging (MFI) for further fault isolation. A resistive or nonlinear fail will likely route to TDR...

It is also relatively simple and inexpensive to add an energy dispersive x-ray detector (EDX) to a SEM which then provides a chemical micro-analysis capability (see the chapter on EDX.) This paper provides an overview of how to use the SEM for imaging integrated circuits. A minimum...
