Intel has begun mass production of its 18A process, which utilizes high-NA EUV technology, potentially giving the company a lead over rival TSMC. The 18A process is seen as a key part of Intel's efforts to compete with TSMC, with some reports suggesting it could put Intel on par with its competitor. However, TSMC is also working on its own advanced technology, including a planned 2nm chip release, which could potentially alter the competitive landscape.
