SiC Growth For EVs Is Stressing Manufacturing


The electrification of vehicles is fueling demand for silicon carbide power ICs, but it also is creating challenges in finding and identifying defects in those chips. Coinciding with this is a growing awareness about just how immature SiC technology is and how much work still needs to be done — and how quickly that has to happen. Automakers are pushing heavily into electric vehicles, and t... » read more

How To Use S-Parameters For Power Module Verification


By Wilfried Wessel (Siemens EDA), Simon Liebetegger (University of Applied Sciences Darmstadt), and Florian Bauer (Siemens EDA) Power modules are high-power switching circuits that convert DC- in AC-currents in electric vehicles, renewable energy, and many more applications. New materials [14] and device technologies [14], such as wide bandgap semiconductors, including silicon carbide (SiC) ... » read more

Ramping Up Power Electronics For EVs


The rapid acceleration of the power devices used in electric vehicles (EVs) is challenging chipmakers to adequately screen the ICs that power these vehicles.[1] While progress toward autonomous driving is grabbing the public’s attention, the electrification of transportation systems is progressing quietly. For the automotive industry, this shift involves a mix of electronic components. Amo... » read more

Week In Review: Semiconductor Manufacturing, Test


Global semiconductor sales reached $574 billion in 2022, and U.S. semiconductor companies accounted for sales totaling $275 billion, or 48% of the global market, according to the 2023 Factbook released by the Semiconductor Industry Association (SIA). DRAM and NAND prices likely will continue to fall further this quarter because production cuts have not kept pace with weakening demand, accord... » read more

Week In Review: Semiconductor Manufacturing, Test


South Korea slashed chip production in February by 17.7% compared to the previous month — 41.8% year-over-year, and the sharpest drop since 2008 — according to figures from South Korea’s National Statistics Office. Inventories were up 33.5%, while exports dropped by 41.6%. China launched a security probe into U.S. memory chipmaker Micron in apparent retaliation for U.S. restrictions on... » read more
