What it is
General reference — not yet source-verifiedA wafer prober is semiconductor test floor equipment that brings probe contacts to pads or bumps on a wafer so electrical measurements can be made before singulation. Wafer probers are used to position wafers accurately under a probe interface and to step from die to die during test operations.
How it works
General reference — not yet source-verifiedWafer probers generally hold a wafer on a chuck, align the wafer to a probing location, and move the wafer in a controlled pattern so a probe card or probe head can contact successive die. Wafer probers generally work with external electrical test instrumentation that applies signals and records device responses while the prober handles wafer positioning and contact sequencing.
Where it fits in the process flow
General reference — not yet source-verifiedWafer probing sits in the electrical test flow after wafer fabrication and before assembly singulation and final package test. Wafer probers are used when die still remain on the wafer, allowing screening, characterization, or sort decisions before downstream packaging steps.
Applications
General reference — not yet source-verifiedWafer probers are used for electrical verification of semiconductor devices at wafer level. Wafer probers support activities such as wafer sort, parametric checking, device characterization, and production screening, depending on the test cell and probe interface paired with the machine.
