As the world awaits commercialization of 0.18 micron- technology wafers, a University of Texas (Austin, TX) team led by Grant Willson printed 0.08 micron features on a semiconductor wafer using a 193-nm-wavelength stepper. The Semiconductor Industry Association's roadmap for the market did not expect 0.08 micron features until the year 2009. Experts predicted the development of a new post-optical technology to produce sizes at or below 0.10 micron. However, Willson generated the minute features using an etched-quartz phase-shift photomask produced by DuPont Photomasks Inc. (Round Rock, TX). "I didn't believe it could be done at first," says Willson. "It really works better than my wildest imaginings, and it appears that the process latitude is there to generate smaller features yet."

The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing.
