Power Electronics is a Penton publication. Its expert editors report on the engineering, design and integration of power electronic system applications, such as battery-powered systems, consumer, commercial and industrial power electronic systems; and power systems for electric and automotive transportation. In an August 2, 2017 article, Sam Davis, editor-in-chief, writes that, “Large-scale adoption of wearable devices will depend on availability of two important technologies: improved batteries and higher density transistor circuits. These two technologies have been made possible by semiconductor lithography.” The article describes two recent breakthroughs.

IBM and its research alliance partners, GlobalFoundries and Samsung described a 5 nm transistor at the June 2017 Symposia on VLSI Technology and Circuits conference in Kyoto, Japan. Scientists working as part of the IBM-led Research Alliance at the SUNY Polytechnic Institute Colleges of Nanoscale Science and Engineering’s NanoTech Complex in Albany, N.Y., achieved the breakthrough by using stacks of silicon nanosheets as the device structure of the transistor, instead of the standard FinFET architecture. The article describes how this new chip technology modifies Moore’s Law.

The article also describes how Enovix has built a new battery platform with an orthogonal approach that extends beyond chemistry to modern science and technology disciplines. These disciplines include 3D cell architecture, photolithography and solar-grade wafer production processes. The result is a new lithium-ion battery with increased energy density and improved safety.
