Is there an end to transistor area density shrinkage?

Moore’s Law is quoted in many different forms.  Basically, area density is a primary focus.  If the difference between generations in a 30% reduction in dimensions, then the area for a transistor (70% by 70%) is reduced by almost 50% … Continue reading
