A 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.
A 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.
Wafer 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.
Wafer 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.
