“A powerful light source bigger than a London double-decker bus has set a record: it can create structures on a silicon wafer that are just 8 nanometres (nm) wide. Those are thought to be the smallest ever made in a single step by a commericial chip-patterning system. According to the system’s manufacturer, it could be used to make computer chips patterned with 2.9 times more transistors than chips produced with the previous generation of the light sources used for this purpose.”
