Device Fabrication Group

The application of modern micro- and nanofabrication techniques to superconducting and cryogenic electronics is enabling new capabilities and applications.

Members of the Device Fabrication Group use the Boulder Microfabrication Facility to make novel sensors and readout circuitry. Standard circuits include Transition-Edge Sensors (TESs), Microwave Kinetic Inductance Detectors (MKIDs), Superconductor-Insulator-Superconductor (SIS) junctions, Normal-Insulator-Superconductor (NIS) junctions, Superconducting Quantum Interference Devices (SQUIDs), microwave feedhorns, and parametric amplifiers. The Device Fabrication Group frequently develops new processes and techniques in order to provide new capabilities to the Quantum Sensors Division and its collaborators. One present area of innovation is integrating multiple types of circuits on a common substrate. Examples include combining NIS tunnel junction refrigerators with TES sensors and combining microwave SQUID multiplexers with TES sensors.

Projects and Programs

Long Wavelength Sensors and Applications

Ongoing
Our project designs and micro-fabricates custom devices that achieve sensitivity at fundamental limits and are based on the principles of superconductivity. We often work in large collaborations to apply these devices to challenging measurements of high scientific interest, such as those which
