Forward looking is about 6k$ per wafer. There are 100 fields, and 8 devices per field (at 100mm2). So, about $10. Assume 80pct yield, and we are at a minimum of $12.
16B$ is 1m wafers per year for a foundry. About 7B in litho tools, 2B in dep, 1B in CMP, 5B in etch, and 1B in I&M. I am assuming about 70 litho layers, EUV moderate, significant double patterning.
Anyway, I don't see a way for $1 for any useful sized device at forward looking nodes. That is why the ecosystem needs apple, quallcomm and Nvidia to push performance on the early end.
