Why Are S-Parameters Superior For Power Module Optimization?

By Siemens EDA - 05 Oct, 2023 - Comments: 0

A power module is a high-power switching circuit – used in electric vehicles, renewable energy, photovoltaics, wind, and many more applications – that uses insulated gate bipolar transistors (IGBT) or metal-oxide-semiconductor field-effect transistors as switching elements. This paper discusses the difference in power module simulation using lumped elements and S-Parameters. Using a simple ... » 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

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

Silicon-based Power Semis Face Challenges

By Mark LaPedus - 17 Feb, 2022 - Comments: 0

Suppliers of power semiconductors continue to develop and ship devices based on traditional silicon technology, but silicon is nearing its limits and faces increased competition from technologies like GaN and SiC. In response, the industry is finding ways to extend traditional silicon-based power devices. Chipmakers are eking out more performance and prolonging the technology, at least in th... » read more

China Accelerates Foundry, Power Semi Efforts

By Mark LaPedus - 22 Nov, 2021 - Comments: 4

China has unveiled several initiatives to advance its domestic semiconductor industry, including a new and massive fab expansion campaign in the foundry, gallium-nitride (GaN), and silicon carbide (SiC) markets. The nation is making a big push into what it calls “third-generation semiconductors,” which is a misnomer. The term actually refers to two existing and common power semiconductor... » read more

Dynamic in-chip current distribution simulation technology for power device layout design

By Technical Paper Link - 12 Nov, 2021 - Comments: 0

Abstract: "This paper reports an in-chip current distribution verification technology for power devices that takes into account the effect of layout parasitics. The proposed method enables verification of dynamic current distribution in a chip considering the influence of layout parasitics from the initial stage of device development by brushing up each element technology of TCAD, Spice mode... » read more

Gearing Up For Next-Gen Power Semis

By Mark LaPedus - 16 Sep, 2021 - Comments: 0

After years in R&D, several vendors are moving closer to shipping power semiconductors and other products based on next-generation wide-bandgap technologies. These devices leverage the properties of new materials, such as aluminum nitride, diamond, and gallium oxide, and they are also utilized in different structures, such as vertical gallium-nitride power devices. But while many of thes... » read more

SiC MOSFETs In The Landscape Of Modern Power Devices

By Peter Friedrichs - 08 Apr, 2021 - Comments: 0

Over the years, low losses possible by high breakdown field made silicon carbide (SiC) MOSFETs extremely popular amongst engineers. At present, they are mostly used in areas where IGBTs (Insulated Gate Bipolar Transistors) have been the prevailing component of choice before. But which role do SiC MOSFETs play in today’s landscape of power devices? With SiC MOSFETs (Metal-Oxide-Semicond... » read more
