4142 Parametric Analyzer
The Keysight/Agilent 4142 Parametric Analyzer includes SMU modules such as the HP41421B (100V), HP41420A (200V), HP41422A (HCU), and HP41423A (HVU), all with calibration.[1]
What it is
The Keysight / Agilent 4142 Parametric Analyzer is a semiconductor test and probe instrument.[1]
How it works
General reference — not yet source-verifiedA parametric analyzer applies electrical bias to semiconductor devices and measures current and voltage behavior to characterize device parameters.
A probe-based parametric test setup uses probe contacts to connect the instrument to wafers or devices before packaging.
Where it fits in the process flow
General reference — not yet source-verifiedA parametric analyzer fits into electrical characterization and wafer-level test flow.
A probe-based analyzer is used after device fabrication and before final assembly when electrical measurements are needed at the die or wafer level.
Applications
General reference — not yet source-verifiedA parametric analyzer is used for semiconductor device characterization, leakage measurement, threshold-related measurements, and other electrical tests on transistors and similar structures.
A probe-based parametric analyzer is used on wafers, dies, and test structures during development, qualification, and production test.
