Provisional entry — research in progress
This page was generated automatically from cited public sources and hasn't completed the full research pass yet. Every specification shown carries its source; more detail is added as research completes.
The Keysight/Agilent 4073A is a parametric tester.[1]
What it is
Where it fits in the process flow
General reference — not yet source-verifiedParametric testers are used after wafer fabrication is complete, typically at the end-of-line (EOL) electrical test step. The tester evaluates test structures that are embedded in the wafer scribe lines or dedicated test areas. The data from parametric testing is used to monitor and control the manufacturing process, providing feedback to earlier process steps such as lithography, etch, and deposition.
Applications
General reference — not yet source-verifiedParametric testers are used for process control and device characterization in semiconductor manufacturing. The measurements support yield analysis and process optimization for various device technologies. The applications include testing of transistors, interconnects, and other on-chip structures.
