As the features on computer chips become increasingly smaller, finding ways to fabricate the chips has become a big challenge. In a new study, researchers from MIT have demonstrated that certain molecules can be deposited on mostly empty chips, where they arrange themselves into patterns that form the outlines of tiny functioning circuits. Researchers Karl Berggren, the Emanuel E. Landsman Associate Professor of Electrical Engineering, and Caroline Ross, the Toyota Professor of Materials Science and Engineering, have published their new method in a recent issue of Nature Nanotechnology.
