Material science is the basis of all semiconductor technology, says former Intel Chairman of the Board Craig Barrett. And during his 35-year stint with one of technology’s most established firms, Barrett has learned that Moore’s Law (Intel founder Gordon Moore’s prediction that the number of transisters in an integrated circuit will double every 18 months) is still applicable now, 40 years after it was written. And though it will eventually have to change, it will likely remain relevant for another 15 years or more.
