Wafer-scale two-photon lithography Researchers from Lawrence Livermore National Laboratory (LLNL) and Stanford University demonstrated a two-photon lithography (TPL) platform for wafer-scale manufacturing. The TPL platform uses large arrays of metalenses to split a femtosecond laser into more than 120,000 coordinated focal spots that write simultaneously across centimeter-scale areas. The a... » read more

Week In Review: Semiconductor Manufacturing, Test


This week saw more fallout from U.S. export controls: SK hynix may consider selling its memory chip production facilities in China if recently imposed controls make it too difficult to continue operations there, according to Nikkei Asia. "As a contingency plan, we are considering selling the fab, selling the equipment or transferring the equipment to South Korea," said Kevin Noh, SK hynix ... » read more

Power/Performance Bits: Jan. 26


Neural networks on MCUs Researchers at MIT are working to bring neural networks to Internet of Things devices. The team's MCUNet is a system that designs compact neural networks for deep learning on microcontrollers with limited memory and processing power. MCUNet is made up of two components. One is TinyEngine, an inference engine that directs resource management. TinyEngine is optimized t... » read more

Manufacturing Bits: May 9


China’s quantum computer In its latest achievement, China has built a quantum computer. With its technology, the University of Science and Technology of China and Zhejiang University claimed to have set two records in quantum computing. In classical computing, the information is stored in bits, which can be either a “0” or “1”. In quantum computing, information is stored in quant... » read more
