SiC Demand Growing Faster Than Supply
By Mark LaPedus - 23 May, 2019 - Comments: 2

The silicon carbide (SiC) industry is in the midst of a major expansion campaign, but suppliers are struggling to meet potential demand for SiC power devices and wafers in the market. In just one example of the expansion efforts, Cree plans to invest up to $1 billion to increase its SiC fab and wafer capacities. As part of the plan, Cree is developing the world’s first 200mm (8-inch) SiC f... » read more

Detecting malware with power monitoring Engineers at the University of Texas at Austin and North Carolina State University devised a way to detect malware in large-scale embedded computer systems by monitoring power usage and identifying unusual surges as a warning of potential infection. The method relies on an external piece of hardware that can be plugged into the system to observe and m... » read more

Trade More trade news: "The Trump administration is hiking duties on $200 billion worth of Chinese products to 25% from 10%," according to CNBC. The following is attributed to Gary Shapiro, president and CEO of the Consumer Technology Association (CTA), in response to President Trump’s plan to increase tariffs on $200 billion worth of Chinese imports to 25%: “The president is seeking a bet... » read more

5G Heats Up Base Stations
By Kevin Fogarty - 07 May, 2019 - Comments: 4

Before 5G can be deployed commercially on a large scale, engineers have to solve some stubborn problems—including how to make a hot technology a whole lot cooler. 5G-capable modem chipsets are already on the market from Qualcomm, Samsung, Huawei, MediaTek, Intel and Apple, with some 5G service (LTE-Advanced/LTE-Advanced Pro) available in the U.S. But still mostly missing from the 5G equati... » read more

How Do I Know? A Machine Told Me So
By Judy Davies - 09 Apr, 2019 - Comments: 0

More than 375 years ago, René Descartes wrote “I think, therefore I am.” And “Think” has been a slogan used by no less a technology giant than IBM for more than a century. The thought process has been a defining aspect of humanity since our beginning. But now technologists are working to imbue that capability into machines through artificial intelligence. Programming computers is no... » read more

Connected Cars: From Chip To City
By Ann Mutschler - 01 Nov, 2018 - Comments: 0

As the automotive industry moves closer to autonomous vehicles, ecosystem players are focusing on the infrastructure pieces needed to make autonomous technology a reality for the first adopters, which are most likely commercial fleets. Vehicle-to-infrastructure (V2I or v2i) is a communications model that allows vehicles to share information with the components that support a country's hi... » read more

Manufacturing Bits: April 10

Higher power GaN Imec and Qromis have announced the development of a new gallium nitride (GaN) substrate technology that enables power devices at 650 volts and above. GaN is an emerging technology for power semiconductor applications. Based on a GaN-on-silicon technology, GaN-based power semis operate at 650 volts and above. In simple terms, the buffer layers between the GaN device and the ... » read more

Mixing 4G And 5G
By Mike Rosa - 15 Mar, 2018 - Comments: 0

5G networks will impact the number and types of ICs in end-user devices and the base stations used to transmit the signals (including the repeaters that rebroadcast those signals). And this is before we begin to consider the technology impact to the infrastructure required to support the data generated in a 5G ecosystem (servers, memory and so on). First, 5G is expected to transmit up to 10 ... » read more

LiDAR Goes Back To The Future
By Jeff Dorsch - 12 Mar, 2018 - Comments: 0

LiDAR is emerging as an increasingly important piece of the enabling technology in autonomous driving, along with advanced computer vision and radar sensor chips. But LiDAR systems also are finding their way into a variety of other applications, such as industrial automation, including robotics, and unmanned aerial vehicles. Advanced mapping is another rapidly growing market for LiDAR, which... » read more

Manufacturing Bits: Feb. 6
