ASML - Double Patterning: the dual carriageway to smaller chip

Chipmakers always try to make electronic circuits smaller. Why? Because fitting more transistors into the same area means chips can do more, work faster, use less power, store more data and cost less (Moore's law). That means better MP3 players, digital cameras, cell phones and computers. ASML provides chipmakers with lithography systems to 'print' chips. And double patterning is the latest printing technology to continue shrinking chips, allowing features down to 32 nanometers.
