Denser, more powerful computer chips possible with plasmonic lenses ...(gher resolution than conventional photol...)

gher resolution than conventional photolithography and without the need for a lithography mask. However, those techniques - electron beam lithography, scanning probe lithography and focused ion-beam lithography - work at a snail's pace compared to the flying plasmonic lens system, said the UC Berkeley researchers.

Zhang noted that the flying head design is not limited to plasmonic lenses. His lab has been developing metamaterials - composite materials capable of bending electromagnetic waves in extraordinary ways - into lenses that can be used for nano-optic imaging and other applications.

"I expect in three to five years we could see industrial implementation of this technology," said Zhang. "This could be used in microelectronics manufacturing or for optical data storage and provide resolution that is 10 to 20 times higher than current blu-ray technology."
