§ 231.118 Semiconductors critical to national security.

Semiconductors 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.
