    摘要: In copper plating using a damascene method, in order to prevent cost rise, dishing, erosion and the like due to the protrusion of plating on the dense wiring area to increase the time for CMP polishing, the copper plating is performed so that the current step of the copper plating has only one step for flowing current in the direction opposite to the direction of growing the plating as shown in FIG. 1. In this time, this opposite direction current step is performed under the condition of a current-time product within a range between 1.0 and 120 mA×sec/cm2.

    摘要: A liquid precursor for forming a thin film of ferroelectric metal oxide in an integrated circuit contains metal oxides in excess of the stoichiometrically balanced amount. When the precursor comprises strontium, bismuth, tantalum and niobium for forming strontium bismuth tantalum niobate, the precursor contains excess amounts of at least one of tantalum and niobium. Capacitors containing thin films of layered superlattice material made from a precursor containing excess tantalum and niobium show good polarizability and low percentage imprint after 1010 negative polarization switching pulses at 75° C., and after 109 negative polarization switching pulses at 125° C.
