A parametric tester measures electrical characteristics of semiconductor structures on a wafer. A test and probe system commonly combines electrical instrumentation with wafer contact through probes so that devices or test structures can be evaluated before singulation. Parametric test is commonly used to monitor process behavior, verify device characteristics, and screen wafer level electrical performance.
A parametric test and probe system typically brings probe contacts onto pads or test structures on a wafer and applies controlled electrical stimuli while measuring the response. A system of this class generally supports current and voltage measurements used to characterize device behavior and process related structures. The resulting data is used to extract electrical parameters from transistors, resistors, capacitors, diodes, and dedicated monitor patterns.
Parametric test and probe tools sit in the electrical characterization part of semiconductor manufacturing and development. A tool of this class is used after wafer fabrication has created conductive and active structures that can be contacted at probe pads. A parametric tester is commonly used before dicing and packaging so that wafer level device and process behavior can be checked directly on the substrate.
Parametric testers are used for wafer level electrical characterization in semiconductor process control, device development, and failure analysis support. A tool of this class is applied to monitor line and contact behavior, transistor characteristics, leakage behavior, and other electrical properties of process control structures. Parametric probing is also used to compare process splits, confirm integration changes, and track stability across production flows.
