Superconducting integrated circuits (ICx) have recently demonstrated record breaking performances in direct digitization and channeling of RF signals for military and satellite communications in frequency bands from HF to X-band (8-12 GHz) Superconducting ICs offer unparalleled clock frequency of 30 GHz that very soon is going to be increased above 50 GHz allowing for a direct digitization of signals in the K-band (12-18 GHz), K-band (18-26 GHz), and beyond. Multi-channel all-digital RF receivers and other complex RF systems for the Navy, Army and other DoD components can be built by using mult-chip modules. This requires multiple chips on the module to communicate at full clock rates (>20 GHz) and with low cross-talk. The existing techniques of bumping individual superconducting chips is a slow and low yield manual process based on molten solder dipping. It is proposed to develop and transer to HYPRES a technology of the wafer-scale bumping based on bump evaporation (base) and bump electroplating (option) that would allow for a data transfer rates between superconducting chips in excess of 100 Gb/s with high fidelity and yield. It is also proposed to research and transfer the methods of modeling, experimental evaluation and optimization of high-frequency parameters of bump bonds.
