Power Semiconductors: A Deep Dive Into Materials, Manufacturing & Business


Whether you’re the owner of the average smartphone, commuting on trains, or driving around in a Tesla, you use power semiconductor devices every day. In a technology-dependent world, these devices are everywhere, and demand for more types of chips using different materials is growing. In the past, most engineers paid little attention to power semiconductors. They were deemed commodity, off... » read more

Silicon-based Power Semis Face Challenges


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

Inspecting And Testing GaN Power Semis


As demand for new automotive battery electric vehicles (BEVs) heats up, automakers are looking for solutions to meet strict zero-defect goals in power semiconductors. Gallium nitride (GaN) and silicon carbide (SiC) wide-bandgap power semiconductors offer automakers a range of new EV solutions, but questions remain on how to meet the stringent quality goals of the automotive industry. Among t... » read more

GaN Application Base Widens, Adoption Grows


Gallium nitride (GaN) is beginning to show up across a broad range of power semiconductor applications due to its wide bandgap, enabling fast-charging, very high speeds, and much smaller form factors than silicon-based chips. Unlike silicon carbide (SiC), another wide-bandgap technology, GaN is a lateral rather than a vertical device. GaN tops out at about 900 volts, which limits its use in ... » read more

Gearing Up For Next-Gen Power Semis


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

Week In Review: Manufacturing, Test


Chipmakers Intel posted its quarterly results. But the big question is whether the chip giant will outsource more of its production to the foundries. As reported, Intel has fallen behind TSMC and Samsung in process technology. And Intel may need to outsource some of its chip production to stay ahead. All of this rests on Pat Gelsinger, the new CEO at Intel. Gelsinger will be taking over for... » read more

Week In Review: Manufacturing, Test


Chipmakers and OEMs At next week’s Apple Worldwide Developers Conference, Apple is expected to roll out its long-awaited Arm-based Mac computers. This could provide a boost for Apple’s foundry vendor as well as equipment makers. It’s the worst-kept secret in the industry. As reported by the Apple sites, Apple is moving from Intel’s microprocessors to its own Arm-based chips for th... » read more

Latest IC Outlook: More Uncertainty


So far in 2020, it’s been a difficult period in the semiconductor industry amid the Covid-19 pandemic outbreak and other issues. And heading into the second half of 2020, the industry faces more challenges, if not uncertainty, in the market. Many segments in the semiconductor industry face some headwinds, but there might be some positive news in the equipment business. To be sure,... » read more

Radar Versus LiDAR


Demand is picking up for vision, radar and LiDAR sensors that enable assisted and autonomous driving capabilities in cars, but carmakers are now pushing for some new and demanding requirements from suppliers. The automotive market always has been tough on suppliers. OEMs want smaller, faster and cheaper devices at the same or improved safety levels for both advanced driver-assistance systems... » read more
