Job Description Skill: DFT - DFT (Design for Test) is a specialized domain in the semiconductor/VLSI industry that ensures integrated circuits (ASICs/SoCs) are testable during manufacturing. DFT engineers design and implement test structures such as Scan, ATPG, MBIST, LBIST, and JTAG to improve chip quality, fault coverage, and manufacturing yield.
