  • Abstract
    A low-resistance ohmic-contacts metallurgy has been developed for the modulation-doped Al0.48In0.52As/Ga0.47In0.53As structure for MODFET (HEMT) application. The metallurgy involves we sequentially evaporated NiGeAuAgAu layers followed by transient thermal alloy cycles. This resulted in low transfer resistance ~ 0.20 ± 0.05 ¿ mm to the two dimensional electron gas for alloying temperatures from 410° C to 500°C.
