Take a look at the challenges at 28nm:<p><a href="http:&#x2F;&#x2F;electronicdesign.com&#x2F;digital-ics&#x2F;understanding-28-nm-soc-design-arm-based-cores" rel="nofollow">http:&#x2F;&#x2F;electronicdesign.com&#x2F;digital-ics&#x2F;understanding-28-nm-...</a><p>You&#x27;re right that it&#x27;s damn-near a miracle that they work. The miracle is the investment of literally billions in tooling and projects to figure out how to get it to work. Then, it&#x27;s still so expensive that cutting-edge nodes at 28nm and below where Intel often works are exclusive to only the elite engineers and tools if it&#x27;s anything of significant size.
