In a microbolometer detector the individual transducers in the focal plane array are support by leg members that are attached to the underlying readout integrated circuit (ROIC) chip at locations underneath transducers other than transducer which they support. A variety of configurations are possible. For example, the leg members may be attached to the ROIC chip at locations under adjacent transducers on opposite sides or on the same side of the supported transducer, or at locations underneath transducers that are not immediately adjacent to the supported transducer. In this way the effective length of the leg members and therefore the thermal isolation of the transducer they support can be increased.
