Abstract
Fe-Co alloy can inhibit intermetallic compound (IMC) growth during assembly process as alternative under bump metallization (UBM) to conventional UBM represented by Ni. Results on IMC growth study indicates Fe-Co UBM is scalable to solder bump first level interconnect (FLI) in 10 μm pitch.
