Contrasting single-wafer and batch processing for memory devices

Single-wafer technology has been shown to improve memory device performance and ultimately improve product yield for several front-end-of-line (FEOL) processes. Single-wafer processes that are reviewed include silicon nitride for word-line cap, flash oxide-nitride-oxide dielectric, cell dielectric re-oxidation, and selective oxidation.
