Spectrum 8852

Test systems in this class are electronic production tools used to apply stimuli to semiconductor devices and measure the resulting electrical behavior. Test systems of this class are used to verify device functionality, parametric behavior, and fault conditions before later assembly or shipment. Probe-oriented test configurations commonly interface with devices while the devices are still on wafers or in engineering analysis setups.

Testers of this class operate by driving electrical patterns or bias conditions into a device under test and comparing measured responses against expected results. Testers of this class commonly combine instrument resources, control electronics, interface hardware, and software to execute repeatable measurement sequences. Scan-oriented hardware in this class is used to access internal logic structures or fault-isolation paths during debug and production screening.

Test and probe equipment of this class sits in the electrical verification portion of semiconductor manufacturing and engineering analysis. Test and probe equipment of this class is used after wafer fabrication has created devices and before or alongside later assembly and qualification steps. Test systems in this role provide pass-fail decisions, characterization data, and diagnostic information that guide disposition and follow-on analysis.

Testers of this class are used for electrical verification, fault isolation, scan-based debug, and characterization of semiconductor devices. Testers of this class support work in product engineering, yield analysis, failure analysis, and production test flows. Probe-connected test configurations in this class are applied where direct electrical access to device terminals is needed for measurement or diagnosis.
