What is a DFT engineer?

DFT Engineers, or Design for Test Engineers, are professionals who specialize in designing and implementing test structures and methodologies within integrated circuits (ICs) to ensure their testability and reliability during manufacturing. Their work enables efficient detection and diagnosis of faults in chips, helping to improve yield and reduce production costs. DFT Engineers collaborate closely with design, verification, and manufacturing teams to integrate features such as scan chains, built-in self-test (BIST), and boundary scan into chip designs. Their expertise is crucial for modern semiconductor development, especially as chips become increasingly complex.
