Addressing Trench Structures And Larger Wafers For Power Devices
By Vamsi Velidandla - 07 Nov, 2023 - Comments: 0

Wind power. Rail. Solar energy. And, perhaps most significantly, electric and hybrid vehicles. Together, these four forces are among the major demand drivers for power devices. While silicon (Si) still plays a role in power devices, wide-bandgap compound semiconductors like silicon carbide (SiC) and gallium nitride (GaN) are particularly well-suited for power devices thanks to their higher e... » read more

Intel aims to quadruple capacity for its most advanced chip packaging services by 2025, including with a new facility in Malaysia, per Nikkei Asia. Huawei is building a collection of secret semiconductor fabrication facilities across China to let the company skirt U.S. sanctions, SIA warned in a presentation seen by Bloomberg. It’s acquired at least two existing plants and is building at l... » read more

Power Semis Usher In The Silicon Carbide Era
By Laura Peters - 21 Aug, 2023 - Comments: 1

Silicon carbide production is ramping quickly, driven by end market demand in automotive and price parity with silicon. Many thousands of power semiconductor modules already are in use in electric vehicles for on-board charging, traction inversion, and DC-to-DC conversion. Today, most of those are fabricated using silicon-based IGBTs. A shift to silicon carbide-based MOSFETs doubles the powe... » read more

TSMC, Bosch, Infineon, and NXP will jointly invest in the European Semiconductor Manufacturing Co. (ESMC), in Dresden, Germany, to provide advanced semiconductor manufacturing services. ESMC marks a significant step toward construction of a 300mm fab, which is expected to have a monthly production capacity of 40,000 300mm (12-inch) wafers on TSMC’s 28/22nm planar CMOS and 16/12nm finFET proce... » read more

SiC Growth For EVs Is Stressing Manufacturing
By Anne Meixner - 08 Aug, 2023 - Comments: 0

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 - 06 Jul, 2023 - Comments: 0

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
By Anne Meixner - 06 Jun, 2023 - Comments: 0

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
By Gregory Haley - 12 May, 2023 - Comments: 0

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
