I don't know what all prices might increase and how much
But I remember some consternation a few months ago since Ukraine supplies half the world's neon, and neon is a critical element in chipmaking. Then I saw that even if the neon price went 10x higher it would only increase the cost per wafer by a fraction of a percent, and decided it wasn't a problem after all. Worst case it speeds up the replacement of neon signs with LEDs, since a lot of neon is wasted recharging neon signs that slowly leak (I used to have one in a business I owned)
There are so many very expensive fixed costs going into making chips, the chemicals/gases being talked about would have go up in cost by a LOT to influence what TSMC charges per wafer.
