Toshiba Electronics Europe brought out the TW070J120B power metal-oxide-semiconductor field-effect transistor, made with silicon carbide process technology. The 1200-volt SiC MOSFET is aimed at 400V AC input AC-DC power supplies, bidirectional DC-DC converters for uninterruptible power supplies, photovoltaic inverters and other high-power industrial applications.
Synopsys unveiled the Silicon Lifecycle Management platform, which is paired with the company's Fusion Design Platform to provide on-chip analytics intellectual property to optimize system-on-a-chip device design and deployment. The technology could keep data-center chips from failing or degrading in performance, it was said.
Analog components in application-specific integrated circuits are presenting more quality challenges, Brian Bailey writes. "Analog tuning means you need to be very clear about the performance of the analog circuit, given the context of the entire system, that you need to achieve in silicon," says Sathish Balasubramian of Mentor, a Siemens Business.
STMicroelectronics acquired the assets of SOMOS Semiconductor, a specialist in radio-frequency front-end modules and silicon-based power amplifiers; financial terms weren't disclosed. The purchase adds to the chip company's portfolio of intellectual property and FEMs for applications in 5G cellular communications and the internet of things.
The Semiconductor Industry Association and the Semiconductor Research Corp. unveiled their Decadal Plan for Semiconductors, which calls for the federal government to spend $3.4 billion a year on advanced research and development in microchip technology. The plan emphasizes R&D in communication, energy efficiency, memory and data storage, security and smart sensing.
A research team at the UK's University of Sussex developed an ultrasensitive, wide-range strain gauge by integrating a graphene nanosheet coating with a polydimethylsiloxane core, producing a controlled, structured material similar to rubber and silicone. The PDMS material is already used in a variety of applications, such as aerospace, health care and microfluidics.
GlobalFoundries is talking up the adaptive body bias feature of its 22FDX platform as helpful in developing internet of things devices and wearable gadgets. The platform's low leakage and power capabilities are well-suited for low-power products, the foundry company says.
Delays in the metal interconnects of IC designs are degrading the performance of system-on-a-chip devices, Bryon Moyer writes. Steve Williams of Cadence Design Systems says, "Processor architecture has always been informed by interconnect delays."
Apple announced this week that boxes containing iPhone 12s will not include a charger and headphones, a move being praised in the worldwide struggle with electronic waste. Teresa Domenech of University College London's Institute for Sustainable Resources says, "This could not only help to reduce waste but also would prevent upstream environmental impacts linked to the extraction of primary raw materials, manufacturing and distribution of products."
China's spending on semiconductors is expected to reach $103.1 billion this year, a 15.8% increase compared with 2019, according to experts speaking at the IC China 2020 expo in Shanghai. "In the future, China's semiconductor industry will continue to strengthen cooperation and communication with the global semiconductor industry, expand opening-up and share the fruits of global semiconductor industry development," says Zhou Zixue, chairman of the China Semiconductor Industry Association.
