Abstract
KIDs have become one of the dominant detector technologies in the far-infrared and mm-wave domains for numerous astrophysical fields. Thin-film aluminium presents a fundamental low-frequency limit to their response for KIDs made with this material of approximately 95 GHz. This limit excludes such detectors from fully exploiting 90 GHz band which is commonly studied in cosmology. We present the array-scale performance of KIDs fabricated from a composite material of aluminium and titanium to produce a transition temperature within the range 0.90-1.05 K. We present characterisation of single arrays consisting of approximately 400 KIDs fabricated on a single 100-mm silicon wafer and readout. We examine the performance of these arrays considering fundamental sensitivity, polarisation response, and on the wafer scale due to fabrication factors. We describe the packaging of the wafer and how vibrational noise is minimised. Finally, we show early results from scaling this to the 150-mm wafers
