Abstract
The present invention relates to the lead-zirconate-titanate (PZT) amorphous alloy plating solution which may be used to form a PZT amorphous alloy film having excellent mechanical and physical properties and a method for plating a PZT amorphous alloy using the same. The PZT amorphous alloy plating solution may include a Pb precursor, a Zr precursor, and a Ti precursor. 10˜50 parts by weight of the Zr precursor and 5˜30 parts by weight of the Ti precursor may be included based on 100 parts by weight of the Pb precursor. Accordingly, electrical conductivity can be improved because the PZT amorphous alloy plating solution has a structure which has low crystallinity or which is amorphous. Furthermore, excellent electrical characteristics can be achieved because the PZT amorphous alloy plating solution has excellent conductivity or chemical stability.
