Atomic Layer Etch Expands To New Markets


The semiconductor industry is developing the next wave of applications for atomic layer etch (ALE), hoping to get a foothold in some new and emerging markets. ALE, a next-generation etch technology that removes materials at the atomic scale, is one of several tools used to process advanced devices in a fab. ALE moved into production for select applications around 2016, although the technolog... » read more

High mobility transistor Engineers at the University of Delaware created a high-electron mobility transistor, a device that amplifies and controls electrical current, using gallium nitride (GaN) with indium aluminum-nitride as the barrier on a silicon substrate. Among devices of its type, the team says their transistor has record-setting properties, including record low gate leakage current... » read more

Flexible battery Researchers at ETH Zurich developed a flexible thin-film battery that can be bent, stretched, and twisted without interrupting the supply of power. Key to the battery is a new electrolyte and entirely flexible components. "To date, no one has employed exclusively flexible components as systematically as we have in creating a lithium-ion battery," said Markus Niederberger, P... » read more

Manufacturing Bits: Aug. 20


Making carbon nanotubes with AI Russia’s Skolkovo Institute of Science and Technology (Skoltech) has developed a method to monitor the growth of carbon nanotubes using an artificial intelligence (AI) technology called machine learning. Skoltech used AI to predict the performance of the synthesis of single-walled carbon nanotubes using a chemical vapor deposition (CVD) process. The tec... » read more

Heart-on-a-chip Megan McCain, a USC Viterbi assistant professor in biomedical engineering is a self proclaimed cardiac tissue engineer. She is working to re-create the human heart on a chip. Not the kind of chip that leads to arterial plaque, of course, but the kind that perfectly re-creates the cardiac cells and mechanical forces of the human heart. A slice of glass, the size of a quarter, ti... » read more
