What is 157i? Googling with various helper terms doesn't turn anything up.

As someone with no background knowledge, I first looked up "193i" intel which lead me to the term 193nm immersion lithography. After that doing the same for 157nm was trivial.
Intel first started cheaping out as far back as 2003-2005.
157i could've been almost as good as EUV, at much lower cost, but Intel fully consciously decided to forego it because "nobody can beat us on 193i yet," and of conern that 157i consortium will give superior litho to potential competitors.
