“…Their low heat conductivity and dielectric constant reduce the cross-talk between neighbouring elements in multi-element detectors. As a thin-film material that can be deposited easily and at a low temperature, pyroelectric polymers have certain advantages over ferroelectric ceramic thin films (Coutures et al 1995, Neumann et al 1995. However, their low glass temperatures are severe obstacles for many applications.…”

The state of the art of thin-film pyroelectric infrared (IR) detectors is reviewed covering device physics, material performance, micro-fabrication and device examples. Emphasis is given to special issues related to thin films, such as small heat capacities and the substrate influence on the pyroelectric properties. For the latter, an overview of the hitherto reported values is given. Examples of micromachined IR detectors based on pyroelectric thin films are described. The ultimate limit of micromachined thermal IR detectors is estimated for uncooled operation. It is concluded that the best pyroelectric thin films achieved to date are in principle sufficiently good to approach this limit, meaning that the present performance of pyroelectric thin-film focal plane arrays can still be improved by more than a factor of 10. A comparison of the different principles for IR detection shows that pyroelectricity is indeed one of the most competitive principles for uncooled IR detection. The major obstacle hindering quick industrialization is the fabrication complexity.

We report on fabrication and characterization of three types of pyroelectric thin films: PbZr 0.53 Ti 0.47 O 3 and BaTiO 3 ceramics, PVDF, and polycyclic organic compound (TADPh). A theoretical model of uncooled focal plane array (UFPA) based on pyroelectric thin film integrated with CCD is proposed. The model of UFPA was designed around the heat balance equations and equivalent circuit. A modified technology of integrated structures of multi-element pyroelectric detectors and special-purpose CCD is proposed. There are designer and manufactured a completely monolithic 100 × 100 µm 2 pyroelectric sensor array based on a heat-sensitive film construction lifted slightly above the crystal and also detector specimens with NETD less than 0.2 K (8-12 µm at 300 K and 20 Hz). Derived measurements and investigations allowed us to choose the structure of 2D analogue CCD processor integrated with pyroelectric membrane array.
