What it is

The Electroglas 4090 FX Pathfinder is a test and probe tool.[2]

How it works

General reference — not yet source-verified

A wafer prober positions a wafer under probe contacts and aligns the wafer with the probe assembly before measurement.

A probe-based test tool typically brings fine contacts to pads or other access points on the wafer so electrical characteristics can be measured without singulating the die.

Where it fits in the process flow

General reference — not yet source-verified

A test and probe tool sits in the wafer-level electrical test portion of semiconductor manufacturing.

A probe station generally supports device characterization, parametric measurement, and wafer acceptance testing before later assembly steps.

Applications

General reference — not yet source-verified

Test and probe equipment is used for wafer-level electrical evaluation of integrated circuits and other microelectronic devices.

A wafer prober is used when electrical access to structures on the wafer surface is needed for characterization and process monitoring.
