What it is
The Keysight 4071 is a PCM tester.[1]
How it works
General reference — not yet source-verifiedThe class of probe-and-test equipment evaluates electrical behavior by contacting devices or test structures through probes and applying test stimuli while measuring responses.
Where it fits in the process flow
General reference — not yet source-verifiedProbe-based testers are used during semiconductor test flows to measure wafer-level structures before later assembly or final test steps.
A PCM tester is used on process-control structures that help characterize electrical behavior across a fabrication flow.
Applications
General reference — not yet source-verifiedA PCM tester is used for wafer-level electrical test of process-control monitor structures.
Probe-and-test equipment is used to check semiconductor devices and test patterns before downstream packaging or product screening.
