It's not less chemical intensive at all. Some aqueous processes have replaced more toxic ones. But dissolved copper and solvent waste makes up the majority of ever fabs waste stream. TSMC/Intel etc have made pretty big strides in zero landfill hazardous waste. It just gets recycled and used in other processes internally or by other companies.
I don't know what the Chinese fabs do, so I have no idea if pump their waste out into the environment.
- Kadin 4y ago> dissolved copper You would think that dissolved copper would have some recovery value, given the price of copper. I am reminded of the waste from silver halide photographic processing, which at one point was just dumped into rivers (an unfortunate amount went into the Great Lakes); when the price of silver increased, suddenly it became worthwhile to recover the silver rather than let it go down the literal drain.
