India, Aug. 19 -- Elon Musk's Terafab plans may include a new approach to EUV light generation.

According to Bits and Chips, the facility may adopt free-electron lasers (FELs), instead of the laser-produced plasma (LPP) sources currently used by ASML. Responding to a post on X, Tesla CEO Elon Musk wrote "FEL, FTW" (Free-Electron Laser, For The Win), signaling his support for the technology.

As noted by Cailian Press, the industry currently relies on LPP technology, which uses high-power lasers to strike fast-moving tin droplets, creating high-temperature plasma that emits EUV light at a wavelength of 13.5 nm.

However, Cailian Press highlights two major drawbacks. Only around 0.1% of input electrical energy is converted into EUV output,...
