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

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

Germanium-on-mica Germanium is an element that can be used in various applications in electronics, such as optoelectronics, semiconductors and others. For example, silicon-germanium (SiGe), an alloy of silicon and germanium, is used for making RF chips. In future finFET transistors, some are exploring the idea of using pure germanium for the PFET structure to boost the electron mobility in ... » read more
