Week In Review: Semiconductor Manufacturing, Test


China retaliated against a U.S. embargo on advanced semiconductor equipment exports by restricting exports of gallium and germanium. Both metals are widely used in semiconductors and electric vehicles. Despite export controls for advanced chips and equipment imposed on Chinese foundries by the U.S. and its allies, TrendForce predicts China's 300mm market share likely will increase from 24% ... » read more

Week In Review: Auto, Security, Pervasive Computing


Joby Aviation and Alef Automotive each received a Special Airworthiness Certificate from the U.S. Federal Aviation Administration (FAA) for an electric vertical take-off and landing (eVTOL) aircraft. Joby will now begin flight testing the prototype, and the aircraft will move to Edwards Air Force Base in 2024 as part of a contract with the U.S. Air Force. Alef’s model is the first U.S. govern... » read more

Week In Review: Design, Low Power


Worldwide semiconductor industry sales dropped 21% year-over-year in May to $40.7 billion, mostly driven by decreases in the Americas (-22%), Asia Pacific/All Other (-23%), and China (-29%). But there also were hints of a recovery. The three-month moving average showed a 1.7% increase in sales, with the largest increases in China (+3.9%) and Europe (+2%). “Despite continuing market sluggishne... » read more
