Engineers Roll Up Their Sleeves--and Then Do Same With Inductors
December 13, 2012
On the road to smaller, high-performance electronics, University of Illinois researchers have smoothed one speed bump by shrinking a key, yet notoriously large, element of integrated circuits. Three-dimensional, rolled-up inductors have a footprint more than 100 times smaller without sacrificing performance. The research team used industry-standard 2-D processing to pattern metal lines on a very thin dielectric film before rolling, creating a spiral inductor.

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) 2017, 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.
