What it is
How it works
Where it fits in the process flow
General reference — not yet source-verifiedX-ray metrology and inspection equipment is generally used as an analytical step rather than a material-modification step. Such tools are typically placed around development, qualification, failure analysis, and process monitoring activities where non-destructive structural information can guide decisions before or after fabrication operations.
Applications
General reference — not yet source-verifiedX-ray systems in semiconductor and related laboratory environments are generally applied to structural inspection, material characterization, and non-destructive examination of features that are not directly observable from the surface. Such equipment can support work on layered films, packaged structures, crystalline materials, and other specimens where internal information is important.
