A Roadmap for Optical Lithography

The International Technology Roadmap for Semiconductors is the go-to standard for predicting future technology requirements and driving global research and development in the semiconductor industry. This article serves as your roadmap to what it all means for optical lithography over the next 10 to 15 years.

Night-Shining Clouds

At the junction between day and night lies twilight—one of the most optically rich and aesthetically pleasing times to observe the sky. In deep twilight, long after the sun has set or before it has risen, a fortunate observer can be treated to a startling visual display when clouds appear suddenly, shining in the dark.

Interferometric Synthetic Aperture Microscopy: Microscopic Laser Radar

Using instruments from optical coherence tomography and the principles of synthetic aperture radar, researchers have developed a new method for reconstructing 3-D optical images. Doctors may soon be able to use this approach as a noninvasive diagnostic tool in clinical settings.
