Abstract :
The use of gold metallization in multichip modules (MCMs) has been investigated for the purpose of achieving simplified processing and high reliability. A process has been developed for producing multilayered, gold metallization thin film MCM (MCM-D) structures which reduces the number of processing steps compared to copper metallization. Multilayered gold-polymer and gold-SiO2 test devices have been fabricated to evaluate the electrical and mechanical properties of the structures. The adhesion of a variety of dielectrics has been achieved by blanket coverage of the noble metal with a single step adhesion layer. The processing, performance, adhesion layer, and cost of gold MCM-D structures on silicon substrates have been analyzed
