A wafer prober is equipment used to make temporary electrical contact to devices on a semiconductor wafer for measurement, characterization, and test before the wafer is diced and packaged. A wafer prober typically combines a wafer stage, a chuck, optical viewing, and probe-positioning hardware so test needles or probe cards can contact selected pads or structures on the wafer surface.
Wafer probers hold a wafer on a chuck and move the wafer under optical observation so individual sites can be brought into position for probing. Probe hardware then lands on contact pads or other target structures, allowing external instruments to source signals and measure electrical response at wafer level. Alignment and repeatable stage motion are central functions because the contacts are temporary and must be placed accurately without damaging the device surface.
A wafer is a thin slice of semiconductor used as the substrate for microelectronic devices. A wafer undergoes processes such as doping, ion implantation, etching, thin-film deposition, and photolithographic patterning before the individual microcircuits are separated and packaged.[3]
Wafer probers are used for wafer-level electrical work such as device characterization, parametric measurement, failure analysis support, and process monitoring. Wafer probers are also used when engineers need direct access to structures on the wafer before assembly changes the form factor or hides internal nodes.
