  • Abstract
    A low cost, multilayer Ni/Cu/Ni/Au metallisation system has been developed for MIC applications. Heat treatments after the Cu and Au deposition improves the crystallinity of the system by decreasing the internal stresses. The ring resonator measurements show that the attenuation characteristic of this system is comparable with that of the conventionally used Cr/Au system.
