SiC Demand Growing Faster Than Supply
By Mark LaPedus - 23 May, 2019 - Comments: 1

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

System Bits: April 30

Future batteries could use a graphene sponge Researchers at Sweden’s Chalmers University of Technology devised a porous, sponge-like aerogel, made of reduced-graphene oxide, to serve as a freestanding electrode in the battery cell. This utilization has the potential to advance lithium sulfur batteries, which are said to possess a theoretical energy density about five times greater than lithi... » read more

Electric Cars Gain Traction, But Challenges Remain
By Mark LaPedus - 22 Apr, 2019 - Comments: 2

Battery-powered electric vehicles are expected to reach a milestone in terms of shipments in 2019, but the technology faces several significant hurdles to gain wider adoption in the market. Limited driving range, high costs, battery issues, and a spotty charging infrastructure are the main challenges for battery electric vehicles (BEVs). In addition, there are issues with various power semic... » read more

SiC Chip Demand Surges
By Mark LaPedus - 20 Sep, 2018 - Comments: 0

The silicon carbide (SiC) power semiconductor market is experiencing a sudden surge in demand amid growth for electric vehicles and other systems. But the demand also is causing a tight supply of SiC-based devices in the market, prompting some vendors to add fab capacity in the midst of a tricky wafer-size transition. Some SiC device makers are transitioning from 4- to 6-inch wafers in the f... » read more

Chip Dis-Integration
By Brian Bailey - 14 Jun, 2018 - Comments: 2

Just because something can be done does not always mean that it should be done. One segment of the semiconductor industry is learning the hard way that continued chip integration has a significant downside. At the same time, another another group has just started to see the benefits of consolidating functionality onto a single substrate. Companies that have been following Moore's Law and hav... » read more

The Bumpy Road To 5G
By Ed Sperling - 21 Mar, 2018 - Comments: 1

5G is coming, but not everywhere, not all at once, and not the fastest version of this technology right away. In fact, the probable scenario is that 5G will be rolled out first in densely populated urban areas, starting in 2020 or 2021, with increasingly widespread adoption over the next decade after that. But 5G is unlikely to ever completely replace 4G LTE, just as a smart phone today roll... » read more

Tools Synopsys debuted new versions of its circuit simulation and custom design products. FineSim SPICE provides 2X faster simulation and Monte Carlo analysis speed, CustomSim FastSPICE offers 2X speed-up for post-layout SRAM simulation and maintains multi-core scalability by providing additional 2X speed-up on four cores, and HSPICE delivers 1.5X speed-up for large post-layout designs, accord... » 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

Here Comes High-Res Car Radar
By Mark LaPedus - 20 Nov, 2017 - Comments: 1

A dozen or so startups are developing high-resolution radar chips that use various modulation schemes and processes, such as CMOS, FD-SOI and even metamaterials. In theory, high-resolution radar could boost the capabilities of today’s radar for cars, as well as eliminate the need for a separate LiDAR system. But the technology is still in the research stage and has yet to be proven commerc... » read more

GaN Power Semi Biz Heats Up
By Mark LaPedus - 24 Oct, 2016 - Comments: 0

The market for devices based on gallium nitride (GaN) technology is heating up amid the push for faster and more power efficient systems. Today, [getkc id="217" kc_name="GaN"] is widely used in the production of LEDs. In addition, it is gaining steam in the radio-frequency (RF) market. And the GaN-based power semiconductor market finally appears ready to take off, after several false starts ... » read more
