When producing silicon for use in semiconductor fabrication, manufacturers have to dope the silicon with phosphorous and then anneal the mixture to produce a material that can be turned into a working microchip. As chips get ever-smaller, more and more phosphorous is needed, and current methods can’t take us past 3nm, where TSMC is currently
