Using Photonic Band Gap in Triangular SiC Structures for Efficient Quantum Nanophotonic HW


A new technical paper titled "Utilizing photonic band gap in triangular silicon carbide structures for efficient quantum nanophotonic hardware" was published by researchers at UC Davis. Abstract: "Silicon carbide is among the leading quantum information material platforms due to the long spin coherence and single-photon emitting properties of its color center defects. Applications of silico... » read more

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

Graphene-Based Electronics (Georgia Tech)


A technical paper titled "An epitaxial graphene platform for zero-energy edge state nanoelectronics" was published by researchers at Georgia Tech, Tianjin University, CNRS, Synchrotron SOLEIL, National High Magnetic Field Laboratory and others. “Graphene’s power lies in its flat, two-dimensional structure that is held together by the strongest chemical bonds known,” said Walter de Heer... » read more

High Voltage Testing Races Ahead


Voltage requirements are increasing, especially for the EV market. Even devices that might be considered relatively low voltage, such as display drivers, are now pushing past established baselines. While working with high voltages is nothing new — many engineers can recall yellow caution tape in their workplaces — the sheer number and variety of new requirements have made testing at high... » read more

Week In Review: Semiconductor Manufacturing, Test


Fallout from the new U.S. export controls continues. Under new regulations, companies looking to supply Chinese chipmakers with advanced manufacturing equipment (<14nm) must first obtain a license from the U.S. Department of Commerce. In addition, U.S. persons (citizens and permanent residents) are barred from supporting China’s advanced chip development or production without a license. ... » read more

How Quickly Can SiC Ramp?


Device makers across the globe are ramping silicon carbide (SiC) manufacturing, with growth set to really take off starting in 2024. It’s been almost five years since Tesla and STMicroelectronics threw down the gauntlet with SiC in the Model 3. Now, no one doubts the market pull for electric vehicles, but consumers are still clamoring for better range and faster charging. SiC devices are a... » read more

ORNL: Advantages of Using Wide Bandgap Semiconductor Materials For Extreme Temp & Radiation


Research paper from ORNL (Oak Ridge National Lab) titled "Wide Bandgap Semiconductors for Extreme Temperature and Radiation Environments." Abstract "With their greater voltage breakdowns, higher current limitations, and faster switching speeds, wide bandgap semiconductors are increasing in market application over the traditionally dominant silicon devices. Silicon carbide semiconductors hav... » read more

Research Bits: June 8


Five-second coherence for silicon carbide qubits Researchers from the University of Chicago, National Institutes for Quantum Science and Technology, and Linköping University built a qubit from silicon carbide and was able to retain its coherence, or the length of time the quantum state persists, for over five seconds. “It’s uncommon to have quantum information preserved on these human ... » read more

Wafer Shortage Improvement In Sight For 300mm, But Not 200mm


The supply chain for bare wafers is off-kilter. Demand is appreciably higher than the wafer suppliers can keep up with, creating shortages that could last for years. For 300mm starting wafers, the top five big players — SEH and Sumco of Japan, Siltronic of Germany, GlobalWafers of Taiwan, and SK Siltron of Korea — finally took action over the last year, spending billions on new wafer fac... » read more

Driving Toward More Rugged, Less Expensive SiC


Silicon carbide is gaining traction in the power semiconductor market, particularly in electrified vehicles, but it's still too expensive for many applications. The reasons are well understood, but until recently SiC was largely a niche technology that didn't warrant the investment. Now, as demand grows for chips that can work in high-voltage applications, SiC is getting a much closer look. ... » read more
