Abstract

The effect of excess Pb contents on the etching of PZT thin films and their electrical properties has been investigated. Ferroelectric PZT(53/47) thin films were prepared by the metal alkoxide-based Sol-Gel method, in which they were spin-coating on P7Ti/Si02/Si substrate using the PZT(53/47) stock solutions with various excess Pb contents. Etching of PZT film was performed using planar inductively coupled Ar/Cl$_2$/BCl$_3$ plasma. The etch rate of PZT film was 2450 $\AA$/min at Ar(20)/BCl$_3$(80) gas mixing ratio and substrate temperature of 8$0^{\circ}C$.
