Section 231.118 - Semiconductors critical to national securitySemiconductors critical to national security means:
(a) Semiconductors utilizing nanomaterials, including 1D and 2D carbon allotropes such as graphene and carbon nanotubes;(b) Compound and wide- and ultra-wide bandgap semiconductors;(c) Radiation-hardened by process (RHBP) semiconductors;(d) Fully depleted silicon on insulator (FD-SOI) semiconductors, other than with regard to semiconductor packaging operations with respect to such semiconductors of a 28-nonometerer generation or older;(e) Silicon photonic semiconductors;(f) Semiconductors designed for quantum information systems;(g) Semiconductors designed for operation in cryogenic environments (at or below 77 Kelvin); and(h) Any other semiconductors that the Secretary, in consultation with the Secretary of Defense and the Director of National Intelligence, determines is critical to national security and issues a public notice of that determination.
