Rohm Semiconductor is making silicon carbide power modules for automotive applications in volume production, industry sources say. Taiwan Semiconductor Manufacturing Co. and Vanguard International Semiconductor are fabricating gallium nitride power chip with their respective GaN-on-silicon processes, those sources note.
While Bosch, Denso and Valeo originally dominated automotive lidar patent filings, there is a new crop of contenders in that field, reports Paul Leclaire, an analyst for Knowmade. LG Innotek, Qualcomm and Ricoh have joined the lidar intellectual property fray, along with LeddarTech, Luminar, Quanergy and Velodyne, he says.
China is reportedly speeding up development of the domestic semiconductor industry at a time of heightened trade tensions with the US, Reuters reports, citing two people with direct knowledge of talks among government officials, regulators, trade groups and the National Integrated Circuitry Investment Fund. The discussions come on the heels of the Trump administration barring ZTE from buying chips offered by Qualcomm, Intel and other American chip vendors.
Alibaba Group purchased IC design company Hangzhou C-SKY Microsystems in an effort to boost its chip development. C-SKY specializes in embedded CPUs and has its own instruction set architecture for its chip designs.
University of California at Riverside and University of Georgia researchers came up with zirconium telluride nanoribbons that are said to have very high current density. The one-dimensional nanoribbons made of a van der Waals material could be ideal for use in nanoscale interconnects and transistor channels, they say.
Applied Materials, Tokyo Electron Ltd. and Lam Research are working on self-aligned patterning technologies with multicolor material schemes, Mark LaPedus writes. Regina Freed of Applied Materials said, "You are trying to overlay multiple layers to each other, and they might have errors."
Finding the chip defects caused by extreme ultraviolet lithography processes is one of the new challenges in the advanced patterning technology, this analysis notes. The random process variations known as stochastic effects are producing faulty contacts and pattern roughness in making microchips.
Intel's New Devices Group, formed by CEO Brian Krzanich in 2013, is being shut down after the chip company wasn't able to make much progress in wearable gadgets, such as the Vaunt augmented reality glasses introduced this year. The Information website reports layoffs are likely for the group, which had 200 employees earlier in the year.
Qualcomm has resubmitted its acquisition application to purchase NXP Semiconductors after China's Ministry of Commerce indicated there were too many unfavorable aspects to the $44 billion deal. The move comes at a time of heightened trade tensions between China and the US.
