WDF 12 DP
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.
What it is
General reference — not yet source-verifiedA wafer prober positions a semiconductor wafer beneath a probe assembly so that individual die can be contacted for electrical testing; probers of this class belong to the test and probe segment of semiconductor manufacturing.
How it works
General reference — not yet source-verifiedA wafer prober moves the wafer into alignment with a probe card using a precision stage.
Alignment is performed by comparing wafer fiducials with the probe card pattern through an optical system.
Where it fits in the process flow
General reference — not yet source-verifiedWafer probing is performed after wafer fabrication and before dicing or assembly.
The prober is used in the wafer-sort stage, where devices are electrically tested to determine which die are functional; good die proceed to packaging and final test, while failing die are omitted from downstream assembly.
Applications
General reference — not yet source-verifiedWafer probers such as the WDF 12 DP are used for wafer-level testing of integrated circuits and other semiconductor devices.
Probing is used in manufacturing test, yield analysis, and process monitoring on wafers that have completed front-end processing.
