ASML has made advancements in EUV light source technology, which could lead to a 50% increase in chip production by 2030. The advancements involve doubling the number of tin drops to 100,000 per second and shaping them into plasma using two smaller laser bursts. This technology is used to create smaller and more efficient chips. The exact details of the announcement are unclear, but it appears to be an incremental improvement on existing technology.
