Scientists Develop An Inexpensive Nanofabrication Method
A new technology can rapidly produce low cost prototype circuits, and offer applications in the fields of medical diagnostics and optoelectronics.
Scientists from Northwestern University have developed a new method for fabricating designs on a nano-scale, called beam-pen lithography (BPL). Using this method, Northwestern’s team patterned 15,000 copies of the two iconic structures of the Chicago skyline-the Willis Tower and the John Hancock Center, simultaneously in just half an hour. BPL consists of a series of tiny pyramid-shaped pens that draw highly precise patterns using light on a light-sensitive material.
