28nm the end of Moore's Law?

The 28nm process is actually the last node of Moore's Law according to EE Times. The site argues that we can continue to make smaller transistors and pack more of them into the same size die, but can't continue to reduce the cost with current technology. Therefore, EE Times claims 28nm will be the most cost-efficient process node for many years to come.

Beyond this point, we can continue to make smaller transistors and pack more of them into the same size die, but we cannot continue to reduce the cost. In most cases, in fact, the same SoC will actually 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," in which he said:

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.
