As they eliminate tiny air bubbles that form when liquid droplets are molded into intricate circuits, a Princeton-led team is dissolving a sizable obstacle to the mass production of smaller, cheaper microchips.
Led by Stephen Chou, the Joseph C. Elgin Professor of Engineering at Princeton, the team worked to troubleshoot one form of nanoimprint lithography, a revolutionary method invented by Chou in the 1990s.
Nanoimprint uses a nanometer-scale mold to pattern computer chips and other nanostructures, and is in marked contrast to conventional methods that use beams of light, electrons or ions to carve designs onto devices.
This technique allows for the creation of circuits and devices with features that are not much longer than a billionth of a meter, or nanometer -- more than 10 times smaller than is possible in today's mass-produced chips, yet more than 10 times cheaper. Because of its unique capabilities and reasonable cost, nanoimprinting is a key solution to the future manufacturing of computer chips and a broad range of nanodevices for use in optics, magnetic data storage and biotechnology, among other disciplines.
