Microfabrication Developments for future Instruments using KID Detectors

Abstract : The NIKA2 instrument, operating at the 30 meters telescope of the IRAM, demonstrates that the aluminum LEKID technology is a state of the art solution for detectors dedicated to millimeter wave astronomy. Following this path, several instrumental projects envisage today the use of the LEKID technology. For covering the full 60 GHz ? 600 GHz band, of interest for CMB-oriented experiments, we are exploring new materials and solutions. Bi-layers or tri-layers of titanium and aluminum are used to address the 60 GHz ? 100 GHz range. Tantalum and vanadium are tested with aluminum to optimize the responsivity in the high end of the band. We present our latest results on such multilayers and materials. Furthermore, we will present an update on our development of silicon optical lenses, to reduce the high frequency photons absorption. In order to minimize the boundary re ections at the silicon, we introduce the thermal-compression process to add anti-re ection layers on curved surfaces.
