Computer chips are now designed to find their own defects
Finance
The world's most advanced microchips now act as their own quality control inspectors, identifying microscopic flaws that are invisible to the human eye.
Modern semiconductors have become so complex that they are now designed to hunt for their own manufacturing errors. As transistors shrink to just 2 nanometers wide—roughly the width of a single strand of human DNA—traditional inspection methods fail. To solve this, companies like Lasertec use extreme ultraviolet light to scan for defects that would otherwise ruin a multi-billion dollar production run.
