Bolometers structure superconductor-insulator-normal metal-insulator-superconductor (SINIS) with suspended absorbers are developed and fabricated. Cu, Pd, Hf are investigated as a normal metal film. Bolometers are integrated with planar double slot and log-periodic antennas. Optimized design and manufacture of the bolometer technology will eliminate the suppression of superconducting gap by proximity effect at the edges of the tunnel junctions bordering the normal metal. Current-voltage characteristics and optical response from blackbody radiation were measured at temperatures of 100-300 mK.
