P 12 XLn
What it is
General reference — not yet source-verifiedA test and probe system is a semiconductor inspection tool that brings electrical probes into contact with pads, bumps, or other test structures on a wafer or die. It is used to evaluate device behavior before full packaging or further downstream processing.
Machines of this class combine precision motion, alignment optics, probe hardware, and measurement interfaces so that electrical test signals can be applied and read back at defined locations on the wafer surface.
How it works
General reference — not yet source-verifiedThe class typically relies on fine alignment, stable stage motion, and repeatable contact mechanics so that the same sites can be revisited and measured consistently. The resulting data is used to check continuity, functionality, parametric behavior, or the presence of defects in the electrical pathway.
Where it fits in the process flow
General reference — not yet source-verifiedTest and probe equipment is used in semiconductor manufacturing and laboratory evaluation where electrical verification is needed before or between later process steps. It generally sits in the inspection and characterization portion of the flow, supporting wafer-level decision making.
Applications
General reference — not yet source-verifiedThis class of machine is used for wafer acceptance checks, parametric characterization, yield screening, and failure analysis support. It is also used to identify functional and electrical anomalies on patterned wafers or device test structures.

Frequently asked questions
What is a test and probe system used for?General reference — not yet source-verified
It is used to make temporary electrical contact to semiconductor devices or wafer test sites so that measurements and pass or fail checks can be performed.
What does the probe assembly do?General reference — not yet source-verified
The probe assembly carries the contact tips that touch the wafer or device pads and transfer test signals between the sample and the measurement system.
Where does this class of tool fit in semiconductor manufacturing?General reference — not yet source-verified
It is used in the testing and inspection part of the process flow, where electrical behavior is verified before later integration or packaging steps.
What kinds of results do these systems produce?General reference — not yet source-verified
They produce electrical measurement data such as continuity, functionality, and device parameter information, depending on the test setup.
Why is alignment important in probe testing?General reference — not yet source-verified
Alignment is needed so the probe tips land on the intended contact points and make reliable, repeatable electrical contact without damaging the test site.
