Researchers from MIT, KAUST, PhotonFoundries, and MITRE have published a paper titled "Foundry-Enabled Patterning of Diamond Quantum Microchiplets for Scalable Quantum Photonics." The paper introduces a manufacturing approach that brings diamond quantum photonics closer to industrial production by using high-precision silicon masks fabricated via commercial semiconductor foundries. This method allows for the production of hundreds of diamond "quantum microchiplets" with improved optical performance and controlled interaction with quantum emitters. The chiplet format enables defective devices to be replaced and integration with existing photonic and electronic circuits, paving the way for large-scale quantum photonic systems.

More details emerge about how Intel now earns more revenue from each wafer by looking to the edges — analyst reports say reduced yield variability across each wafer leads to more sellable CPUs

Intel has seen improved revenue per wafer by reducing yield variability across each wafer, resulting in more sellable CPUs. The company's focus on tightening yield distribution across the wafer edges has led to increased margins and productivity. By implementing edge-specific process correction methods, Intel can extract more high-quality and sellable dies from a single wafer. These improvements are node-independent and have been attributed to disciplined execution improvements under new manufacturing leadership. Intel's efforts have led to better output and demand for CPUs, with even lower-quality chips now being sold as viable products.

Scientists create electronic devices that function reliably at extreme temperatures from 500 degrees Celcuis to absolute zero — advanced semiconductor material unlocks new possibilities in space tech and quantum computing

Scientists at KAUST have developed electronic devices made of gallium oxide that can function reliably in extreme temperatures from near absolute zero to 500°C. These devices have potential applications in space tech and quantum computing due to their ability to withstand extreme temperature swings. By using ultrawide-bandgap semiconductor beta-gallium oxide and heavily doping it with silicon atoms, the researchers created devices that can maintain electrical conduction even in cryogenic conditions. The team built transistors and logic inverters that operated reliably at temperatures as low as 2K, paving the way for the development of temperature-resistant devices for various technological applications.
