Abstract

We have examined the influence of bump shape and bonding pressure on low temperature electrical properties of indium bump connections including transition temperature, normal resistance, and superconducting critical current. We describe our test structures, bonding process, and methods of characterization. Critical currents greater than 70 mA for indium bump connections with a nominal bump size of 17 µm by 17 µm are observed.
