What it is
The Hitachi S 2150 is a scanning electron microscope (SEM) classified as a metrology and inspection tool for semiconductor manufacturing.[1][2]
How it works
General reference — not yet source-verifiedA scanning electron microscope generates a finely focused electron beam by thermionic or field emission from an electron gun. The beam is demagnified and scanned across the sample surface in a raster pattern by electromagnetic lenses and scanning coils.
When the primary electron beam strikes the sample, it generates secondary electrons, backscattered electrons, and characteristic X-rays. Detectors collect the secondary or backscattered electrons, and the intensity of the signal at each beam position is used to build an image. The high depth of field and wide range of magnifications make SEMs suitable for inspecting topography and identifying defects on processed wafers.
Where it fits in the process flow
General reference — not yet source-verifiedUpstream of the SEM are the defect detection tools (e.g., bright-field or dark-field optical inspectors); downstream, the defect classification data feeds yield management systems that guide process adjustments. The SEM may also be used off-line for failure analysis of individual die or packaged parts.
