Electrical, yield and defect results from dedicated test chips carrying yield structures, memory arrays, ring oscillators and other monitors, used to learn about a new process or memory array before products.
Report Work product in the Process technology (node) lifecycle and the Memory product lifecycle (DRAM, NAND and HBM)
It is the main evidence of process or array yield before products are built. Yield learning without structured data cannot localise defect sources, and the yield readiness gate is judged on guesswork.
