Accurate estimation of manufacturing variations can improve circuit performance
New Delhi, April 12 th (India Science Wire): Silicon-based electronic circuits are getting smaller. The
Taiwanese manufacturer TSMC currently makes chips with the smallest feature of the circuit measuring
just 7 nanometers, with millions of such components packed on a single chip. The process of
manufacturing such ultra-dense circuits is complex. Despite world-class control, there are tiny
fluctuations in the nanoscale dimensions. Thus, each transistor is slightly different from another across
chips and even on the same chip. A circuit designer must account for such variations to ensure that each
of the billions of chips produced works as expected. Thus, a model to account for such nanoscale
variations in manufacturing is essential.
