Abstract

We have developed a Nb/Al/AlO‡/Nb trilayer process aimed towards integration of RSFQ and qubit circuits. The emphasis is to provide a process enabling RSFQ operation at sub-100 mK temperatures required for qubit operation. In this paper we describe the main properties of the process. We also present experimental characterization data and in particular introduce a method of determining the critical current density by wafer level room temperature measurements.
