We can still make transistors smaller but not cheaper
We have been hearing about the imminent demise of Moore’s Law quite often recently. Most of those predictions have been targeting the 7nm node and 2020 as the end point. But we need to recognize that 28nm is actually the last node of Moore's Law, beyond which we can make smaller transistors and pack more of them into the same die size but we can not reduce the cost, and in most cases, the same SoC will have a higher cost!
The famous Moore's Law was presented as an observation by Moore in his 1965 Electronics paper "The future of integrated electronics". Quoting: "The complexity for minimum component costs has increased at a rate of roughly a factor of two per year. Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years." Clearly Moore's Law is about "The complexity for minimum component costs", and the minimum component cost will be at the 28nm node for many years, as we will detail in the remainder of this blog.
