It's also turned out that carbon nanotubes are toxic in a similar fashion to asbestos. While a completed chip would be sealed, it does raise concerns about the safety of manufacture. Similar concerns have been raised about graphene.
- runeks 3y agoI’m not convinced that’s a problem, since chip fabs require people to wear cleanroom suits anyway.
- da_chicken 3y agoIt's possible, but cleanroom suits are primarily designed to protect the product from the employees. They keep foreign contaminants out of the manufacturing environment. They're not necessarily capable of protecting the employees from the hazards of the manufacturing environment itself, nor do they necessarily account for the removal of hazardous material before venting the production area to the atmosphere. It might further add to the costs of the fabrication facility.

- lazide 3y agoAdding hepa filters on exhaust (and issuing respirators) and not just intake would not budge the cost of a chip at all.
- WJW 3y agoHonestly asbestos (and by analogy graphene) would be some of the more benign chemicals involved in semiconductor manufacturing. It regularly uses carcinogens, things that will cause miscarriages in pregnant women and acids strong enough to cause bone damage after being absorbed through the skin.
