As electronics devices become smaller and smaller, the challenges faced when designing them become questions of scale. Semiconductors, for example, have a thin, 35-angstrom layer of silicon dioxide used as an insulating material. As the chips get smaller, the insulating material must also proportionally shrink. But once the thickness falls below 20 angstroms, the silicon layer is no longer an effective insulator. Researchers at Motorola, Pacific Northwest National Labs, and Oak Ridge National Lab (ORNL) are joining forces for development of new insulating materials from crystalline oxides on silicons that are expected to have higher dielectric strengths and higher capacitance. "We are able to eliminate one of the hurdles to continuing the current rate of growth in the semiconductor industry," says Rodney McKee, a researcher at ORNL Metals and Ceramics Div. "If Moore's Law continues to hold true, we'll need the new insulating materials in just a few years." For more information, call Jan Haerer at (865) 241-7613.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
