5. Rare-earth magnet uses less neodymium
According to the Korea Institute of Materials Science, the performance of commercial grade 42M magnets can be achieved with approximately 30% less neodymium than before. More cheaper rare earth cerium is the answer, but making this substitution has proven difficult. “In order to develop a permanent magnet with reduced neodymium content, the cerium content must be increased,” KIMS said. “Until now, with the increase in cerium content, it was not able to prevent the deterioration of magnetic properties.”
4. Taiwan accounts for 26% of global chip revenue
Taiwan held a 26% market share of semiconductor revenue in 2021, according to TrendForce, second only to the United States. The island’s IC design and packaging and testing industries account for a global market share of 27% and 20%, ranking second and first in the world, respectively. Taiwan accounts for 64% of the foundry market, with TSMC possessing the most advanced processing technology. By 2022, Taiwan will account for approximately 48% of the world’s 12-inch-equivalent wafer foundry production capacity.
3. Imec Accelerates High-NA Modeling Development
Imec has made significant progress in preparing the High-NA patterning ecosystem for the imec-ASML Joint High-NA lab, which will focus on the first 0.55NA Extreme Ultraviolet (EUV) lithography prototype tool. Progress is reported in the development of patterning and etching processes, in the screening of new resist and underlay materials, in improved metrology, and in photomask technology. “Imec partners with ASML on High-NA technology as ASML builds its first prototype EUV 0.55NA EXE:5000 lithography scanner,” says Imec CEO.
2. Falling GPU prices raise hopes that shortages will end
GPU prices are down sharply, suggesting that the chip shortage may be coming to an end. 3DCenter reports that AMD’s Radeon RX6000 and Nvidia’s GeForce RTX30 gaming GPUs have been priced from 80% to 20% above MSRP (Manufacturers’ Suggested Retail Price). Susquehanna estimates GPU prices have gone from 76% to 41% above MSRP.
1. Intel is ramping up qubit manufacturing
Researchers from Intel and QuTech – made up of Delft University of Technology (TU Delft) and the Netherlands Organization for Applied Scientific Research (TNO) – created large-scale silicon qubits in the factory Intel’s D1 manufacturing facility in Hillsboro, Oregon. The result is a process that can fabricate over 10,000 arrays with multiple silicon spin qubits on a single wafer with over 95% yield
