Talks about the use of molten tin hit by high-powered lasers to create computer circuits.
Extreme ultraviolet lithography
What it is: Technology to enable small features on computer chips. A high-powered laser hits a microscopic drop of molten tin, turning it to plasma that emits an ultraviolet light. Mirrors focus and direct that light onto a silicon wafer to create tiny patterns for computer circuitry.
What it costs: Each tool costs 100 million euros, nearly $120 million.
Size: A single EUV tool is the size of a school bus and weighs nearly 400,000 pounds - more than 100 cars.
