Manufacturing Bits: Nov. 25


RF carbon nanotubes For years, the industry has been working on logic and memory devices based on carbon nanotubes, although these technologies remain in R&D. Now, there is a new device type using carbon nanotubes--RF. Startup Carbonics has developed an RF-based carbon nanotube technology that operates at frequencies over 100GHz. The technology exceeds the cutoff frequency of todayâ€... » read more

Power/Performance Bits: Nov. 5


Conductive yarn Researchers at Drexel University created an electrically conductive coating for yarn that withstands wearing, washing, and industrial textile manufacturing. Rather than using metallic fibers, the coating is made up of different sized flakes of the two-dimensional material MXene, which was applied to standard cellulose-based yarns. Titanium carbide MXene can be produced in f... » read more

A Different Foundry Model


As the pursuit to produce advanced semiconductors that keep up with the Moore’s Law treadmill becomes more and more challenging, many companies are seeking other ways to provide the next ‘must-have’ electronic products. In fact, many companies have realized that the need for doubling performance is no longer the main attribute necessary to deliver successful solutions for IoT, automotive,... » read more

System Bits: Sept. 3


Microprocessor built with carbon nanotubes Researchers at the Massachusetts Institute of Technology were able to design a microprocessor with carbon nanotubes and fabricate the chip with traditional processes, an advance that could be used in next-generation computers. Work on producing carbon nanotube field-effect transistors has gone on for some time. Fabricated at scale, those CNFETs oft... » read more

System Bits: Aug. 27


A ring of 18 carbon atoms Scientists at IBM Research – Zurich and Oxford University write about allotropes of carbon – the many versions of atomic carbon formations, such as diamonds and graphite. “Carbon, one of the most abundant elements in the universe, can exist in different forms - called allotropes - giving it completely different properties from color to shape to hardness. For... » 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

Power/Performance Bits: June 25


Improving IGBTs Researchers at the University of Tokyo developed a power switching device that surpasses previous performance limits, showing that there may still be gains ahead for the silicon-based devices, which have been thought to be approaching their limits. The team's improved insulated gate bipolar transistor (IGBT) used a scaling approach, and simulations showed that downscaling pa... » read more

Power/Performance Bits: May 21


More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

EUV Mask Gaps And Issues


Semiconductor Engineering sat down to discuss extreme ultraviolet (EUV) lithography and photomask technologies with Emily Gallagher, principal member of the technical staff at Imec; Harry Levinson, principal at HJL Lithography; Chris Spence, vice president of advanced technology development at ASML; Banqiu Wu, senior director of process development at Applied Materials; and Aki Fujimura, chief ... » read more

A Different Kind Of Material World


The semiconductor manufacturing world is poised for big change, and the driver will be materials. Materials always have been a critical factor in semiconductors. Silicon is so important that an entire region of California is named after it. Rare earths have raised fears about nationalistic monopolies. And the shift from aluminum to copper interconnects at 130nm caused one of the most painful... » read more
