The Hybrid Technology Multi-Threaded (HTMT) approach to petaflops computing includes large numbers of ultra-high performance Nb Rapid Single Flux Quantum (RSFQ) processor and memory chips, making it by far the largest active superconducting electronics project in the United States. In order to achieve petaflops, RSFQ circuits with 105 to 106 junctions per chip will be required to operate at clock speeds of 50 to 100 GHz, far beyond the current state of the art. In this paper, we review the state of the art of Nb circuit fabrication and discuss the requirements for significantly improving circuit density and speed
