Despite political and national security concerns about U.S. domestic semiconductor production, American companies continue to account for more than half of the global chip industry’s total spending on research and development, according to the latest annual analysis of R&D expenditures by IC Insights. About 56% of worldwide semiconductor industry R&D spending in 2021 was by companies headquartered in the Americas region—essentially all of them in the U.S. and a large chunk of that coming from Intel (19%, or $15.2 billion last year), says IC Insights’ analysis of research and development trends published in its most recent quarterly update of the 2022 McClean Report service.
