New Technique Makes It Easier to Etch Semiconductors
December 22, 2011
Creating semiconductor structures for high-end optoelectronic devices just got easier, thanks to University of Illinois researchers. The team developed a method to chemically etch patterned arrays in the semiconductor gallium arsenide, used in solar cells, lasers and other optoelectronic devices. Unlike other wet methods, metal-assisted chemical etching works in one direction, from the top down, without damaging the surface like dry etching does.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
