Ramanujam, noted, "We're glad to be offering SanDisk 3D an accurate and cost-
effective patterning synthesis solution that is tailored specifically for
their advanced processes and designed to minimize mask re-spins. Architected for the 65-nm era,
Invarium's layout -to-mask solution represents a superior alternative to
conventional RET/OPC tools and other layout correction techniques for process
effects from mask through etch.
