The electron beam prober (e-beam prober) is a specialized adaption of a standard scanning electron microscope (SEM) that is used for semiconductor failure analysis. While a conventional SEM may be operated in a voltage range of 10–30 keV, the e-beam Prober typically operates at 1 keV. The e-beam prober is capable of measuring voltage and timing waveforms on internal semiconductor signal structures. Waveforms may be measured on metal line, polysilicon and diffusion structures that have an electrically active, changing signal. The operation of the prober is similar to that of a sampling oscilloscope. A continuously looping, repeating test pattern must be applied to the device-under-test (DUT). E-beam probers are used primarily for front side semiconductor analysis. With the advent of flip-chip technology, many e-beam probers have been replaced with back side analysis instruments.

DIY Scanning Electron Microscope - Operation procedure
After getting back from Maker Faire (which is always a hugely enjoyable and inspiring event), I thought that my microscope might need some repairs. As it turned out, I only had to change the filament and tighten some screws that came loose during the trip back from the Faire. The microsc
