EUV Light Makers Playing Catch-Up

In the effort to print ever-smaller transistors, lithography machine suppliers are setting aggressive goals for extreme ultraviolet light sources

4 min read

19 July 2011—Extreme ultraviolet (EUV) light, the sort that’s needed to create the transistors of tomorrow, isn’t so easy to make. For years, the companies building EUV sources have struggled to deliver enough photons to match the output of a few incandescent lightbulbs.

But the days of paltry power could be coming to a close. Suppliers of EUV light say they will soon deliver a big jump in brightness, putting EUV lithography on track to produce ever-smaller transistors and pick up Moore’s Law where existing lithography machines leave off.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
