nitpick: TSMC's EUV process uses lasers to vaporize tin, not lead, into EUV emitting plasma.
- londons_explore 3y agoDoes the tin itself lase? Is the radiation given off from the tin single-frequency and phase coherent?
- foobiekr 3y agoNo. And it doesn’t matter for their use case.
- londons_explore 3y agoseems like a recipe for fragility... The mixtures of wavelengths will make optimizing other parts of the process very hard. And even keeping a consistent mix of wavelengths isn't easy.
