Putting the silicon back in the valley

AI has returned chipmaking to the heart of computer technology

And the technological challenges are bigger than the political ones, argues Shailesh Chitnis

Shrink to fit

The semiconductor industry faces its biggest technical challenge yet

As Moore’s law fades, how can more transistors be fitted onto a chip?

The names are meaningless

Node names do not reflect actual transistor sizes

A favourite way of measuring progress in the chip industry is detached from reality

A Cambrian moment

AI has propelled chip architecture towards a tighter bond with software

It has also been pushed farther towards specialisation

OK (analogue) computer

Researchers are looking beyond digital computing

They are using biology and light to design powerful, energy-efficient chips

The relentless innovation machine

The end of Moore’s law will not slow the pace of change

Semiconductors are likely to continue their transformational role
