Nonvolatile memory devices

Recently, efforts have been devoted to the fabrication and characterization of PbZri- Ti c03 family thin films for their potential applications in nonvolatile memory devices (See Ref. 17, for example). Partly because of the convenient stoichiometry control during processing, it was found that chemical methods, such as sol-gel and metal organic decomposition (MOD), are superior to physical means in many aspects. To appreciate better the science and technology of ferroelectric thin-film fabrication, it is important to give a brief account of the past efforts and the present status and, it is hoped, shed some light on the future.

Ferroelectric materials have numerous microelectronics applications, including capacitors (7,2), nonvolatile memory devices (2-4 electrooptic devices 1,4) and many others (5). The ferroelectrics described in this paper are Pb(ZrxTii x)03 (PZT), BaTi03, and YMn03. Here we investigate the use of a photochemical method for the direct deposition of these complex materials.
