SiC Market Moves Into Overdrive


The silicon carbide (SiC) power semiconductor market continues to heat up in the automotive arena. In recent times, several automotive OEMs have formed a series of alliances with SiC device makers, and for good reason. In a major way, many automotive OEMs are entering or expanding their efforts in the battery-electric car market. SiC power semiconductors are among the key components used ... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs Delphi Technologies is in volume production with a 800 volt silicon carbide (SiC) inverter for next-generation electric and hybrid vehicles. The inverter extends electric vehicle (EV) ranges. It also halves the charging times compared with today's 400 volt systems. In a separate announcement, Delphi Technologies and Cree have announce a partnership to utilize SiC semicon... » read more

Manufacturing Bits: Sept. 3


Modeling SiC defects The Institute of Nuclear Physics of the Polish Academy of Sciences (IFJ PAN) has developed a model that reveals the nature of crystal defects in silicon carbide (SiC). Defectivity is an issue for SiC, a compound semiconductor material based on silicon and carbon. Today, SiC is used to make specialized power semiconductors for high-voltage applications, such as electric ... » read more

Silicon Carbide’s Superpowers


As we enter a new computing era driven by the Internet of Things (IoT), Big Data and Artificial Intelligence (AI), demand is growing for more energy-efficient chips. In this context, we usually think about Moore’s Law and reducing the size of transistors. However, advances in power semiconductors are not governed by node size reduction. Silicon power switches, such as MOSFETs and IGBTs, ar... » read more

200mm Cools Off, But Not For Long


After years of acute shortages, 200mm fab capacity is finally loosening up, but the supply/demand picture could soon change with several challenges on the horizon. 200mm fabs are older facilities with more mature processes, although they still churn out a multitude of today’s critical chips, such as analog, MEMS, RF and others. From 2016 to 2018, booming demand for these and other chips ca... » read more

Wide Band Gap—The Revolution In Power Semiconductors


New government regulations and industry standards are leading companies to adopt wide bandgap (WBG) power solutions, both to reduce their carbon footprint and to meet increasing demand for higher power systems aimed at electric vehicles, renewable energy, datacenters, and other markets. The automotive industry is one of the biggest markets driving demand for WBG power devices. The European U... » read more

Inspection, Metrology Challenges Grow For SiC


Inspection and metrology are becoming more critical in the silicon carbide (SiC) industry amid a pressing need to find problematic defects in current and future SiC devices. Finding defects always has been a challenging task for SiC devices. But it’s becoming more imperative to find killer defects and reduce them as SiC device vendors begin to expand their production for the next wave of a... » read more

SiC Demand Growing Faster Than Supply


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

Week in Review: IoT, Security, Auto


Internet of Things Verizon Communications launched its nationwide narrowband Internet of Things network, saying it covers more than 92% of the U.S. population. “There is a whole universe of smart solutions needing scalable and affordable connections,” Jeffrey Dietel, senior vice president of business marketing and products, said in a statement. “By launching our NB-IoT network, Verizon i... » read more

Electric Cars Gain Traction, But Challenges Remain


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
