How to Build a $20B Semiconductor Fab (2024)
How to Build a $20 Billion Semiconductor FabBrian PotterMay 03, 20244644247ShareIntel fab under construction in Ireland, via Intel IrelandFor the last several decades, one avenue of technological progress has towered over nearly everything else: semiconductors. Semiconductors are materials that can have their conductivity varied by many orders of magnitude, which makes it possible to selectively block and allow the flow of electrons. This property makes it possible to manufacture all sorts of electronic devices, not least of which is the digital computer.

As semiconductor technology has advanced over the past several decades, the cost and size of electronic computation has steadily fallen, making the PC, the internet, and mobile phones all possible.
