Metalorganic liquid precursors were used to examine the effects of processing atmosphere on texture development in oriented Pb(Zr{sub 0.60}Ti{sub 0.40})O{sub 3} thin films. After removal of organic ligands via pyrolysis, the films were heated at 25 degree sign C/min in a 5% H{sub 2}/Ar atmosphere until a switching temperature, after which the atmosphere was switched to pure oxygen. The films were heated to a maximum temperature of 650 degree sign C with switching temperatures ranging from 450 to 600 degree sign C. The degree of (111) orientation in the lead zirconate titanate (PZT) films increased with increasing switching temperature, resulting in highly textured (111) PZT films. These results suggest that atmosphere control plays a significant role in texture development during rapid thermal processing. (c) 1999 Materials Research Society.
