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

South Korea slashed chip production in February by 17.7% compared to the previous month — 41.8% year-over-year, and the sharpest drop since 2008 — according to figures from South Korea’s National Statistics Office. Inventories were up 33.5%, while exports dropped by 41.6%. China launched a security probe into U.S. memory chipmaker Micron in apparent retaliation for U.S. restrictions on... » read more

Using Photonic Band Gap in Triangular SiC Structures for Efficient Quantum Nanophotonic HW
By Technical Paper Link - 03 Apr, 2023 - Comments: 0

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
By The SE Staff - 03 Apr, 2023 - Comments: 0

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

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
By Karen Heyman - 06 Dec, 2022 - Comments: 1

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

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?
By Adele Hars - 21 Jul, 2022 - Comments: 0

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
By Technical Paper Link - 13 Jun, 2022 - Comments: 0

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
By Jesse Allen - 08 Jun, 2022 - Comments: 0

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
