Embedded powerPC 405 & 440-based SoC product qualifications on 45°-rotated substrates

We discuss functionality, performance, power and reliability evaluations of the world´s first SoC products fabricated using IBM 90 nm technology on a 45deg-rotated substrate. We have demonstrated reliable product operational lifetimes with up to 12% improved across die delay variability including 30% product performance improvement and 33% leakage reduction over nonrotated substrate.
