  • Abstract
    BLT thin film capacitor was fabricated by the novel method of chemical mechanical polishing (CMP) process. The electrical characteristics including P-V and I-V of BLT capacitor were damaged by the polishing pressure which is one of the main factors to improve the CMP performance for BLT thin film; therefore, the lower polishing pressure must be selected for the good electrical characteristics although the removal rate was lower.
