Indium Bump Process for Low-Temperature Detectors and Readout

Author(s)
Tammy Lucas, John Biesecker, W.Bertrand (Randy) Doriese, Shannon Duff, Gene C. Hilton, Joel Ullom, Michael Vissers, Dan Schmidt
We describe our indium bump process for low-temperature detectors and associated readout. A titanium nitride under bump metallization layer (UBM) is reactively

CRYOGENIC THERMOMETER BASED ON A TWO-LEVEL SYSTEM (TLS)

NIST Inventors
Michael Vissers , Jordan Wheeler and Maxime Malnou
patent description We have invented a new type of cryogenic thermometer (referred to as two-level-system thermometer or TLS-thermometer) for measurement of temperature below 1 Kelvin. The device consists of a superconducting micro-resonator with dielectric materials containing two-level systems
