  • Publication number: 20170271499
    Abstract: According to various aspects, a thermal-aware finned field-effect transistor (FinFET) may have a design that can substantially reduce hot spot temperatures and resolve other self-heating problems. More particularly, the FinFET design may use aluminum nitride (AlN) fins that can provide a main thermal exit and a source, drain, and channel formed from materials that can spread or dissipate heat, wherein AlN has a high thermal conductivity compared to silicon such that using AlN to form the fins may substantially increase heat flux to a silicon substrate relative to silicon fins. Furthermore, thermal-efficient materials may be used to form the source, drain, and channel structures to further spread heat and decrease hot spot temperatures.
