Automatic test equipment systems are semiconductor test platforms used to apply electrical stimuli to devices and measure the resulting responses. Automatic test equipment systems are used to verify device behavior against test limits during manufacturing and product qualification. Test and probe configurations commonly interface with handling or probing hardware so packaged devices or wafers can be presented to the tester in a controlled sequence.

Automatic test equipment systems route programmed signals from installed instrument resources to the device under test and evaluate measured outputs against pass or fail criteria. Automatic test equipment systems typically combine stimulus generation, voltage and current sourcing, measurement functions, timing resources, and switching paths within a configurable chassis. Test and probe installations commonly use docking hardware to connect the tester to external manipulation or device presentation hardware.

Automatic test equipment sits in the electrical test portion of semiconductor manufacturing rather than in wafer fabrication patterning or deposition steps. Automatic test equipment can be used after wafer processing during wafer sort with probe interface hardware, and it can also be used later for packaged-device test with suitable handling equipment. Automatic test equipment generally follows device fabrication and packaging preparation, and it precedes shipment qualification and binning decisions.

Automatic test equipment is used for electrical characterization, production screening, and functional verification of semiconductor devices. Automatic test equipment supports measurement tasks such as applying signals, sourcing or sensing electrical conditions, and checking whether device responses remain within required limits. Test and probe setups are used where a test program must be executed repeatedly across many devices with controlled contact to package leads or wafer pads.
