Two Chinese startups drew big investment as the country aims to become more semiconductor independent as trade restrictions continue. One company deals in wafers, packaging, and IC design, while the other is focused on AI chips. Quantum computing startups didn't see large investments this month, as most are still very young companies, but the number of them grew with a new university spin-out e... » read more

Test Setup Optimization And Automation For Accurate Silicon Photonics Wafer Acceptance Production Tests

Flexible battery Researchers at ETH Zurich developed a flexible thin-film battery that can be bent, stretched, and twisted without interrupting the supply of power. Key to the battery is a new electrolyte and entirely flexible components. "To date, no one has employed exclusively flexible components as systematically as we have in creating a lithium-ion battery," said Markus Niederberger, P... » read more
