➀ Japanese engineer Tsumoru Shintake has developed a four-mirror EUV system that is over ten times more efficient than current ASML scanners. ➁ The design reduces the number of mirrors from ten to four, cutting EUV light generation power by 92% and lowering manufacturing and maintenance costs. ➂ Despite its efficiency, the setup is unlikely to be commercially adopted due to reduced resolution and smaller field size, according to ASML and Zeiss.
