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 is a piece of test-and-probe equipment used to contact devices on a wafer before singulation. It is part of the wafer-level test flow and is used to present probes to pads or test structures on the wafer surface.
How it works
General reference — not yet source-verifiedA wafer prober positions a wafer on a precision stage and aligns probe needles or probe cards to the target pads or structures. Electrical contact is then made so test signals can be applied and measured at wafer level.
Production probers are built to repeat this contact-and-measure sequence across many sites on a wafer, supporting automated testing and sorting before downstream packaging.
Where it fits in the process flow
General reference — not yet source-verifiedThis class of equipment sits in the wafer test portion of semiconductor manufacturing, after front-end fabrication steps have created devices and before dice are separated and packaged. It is used to identify functional devices and support wafer-level qualification.
