A formed device embedded-type 0402 sized (Ca0.7Sr 0.3)(Zr0.8Ti0.2)O3 (CSZT) embedded capacitor was fabricated for use in embedded printed circuit board. The capacitance and dielectric loss of the CSZT embedded capacitor were 406.1 pF and 0.015, respectively, at 1 MHz. The CSZT embedded capacitor exhibits stable capacitance with varying applied voltage and C Zero G (-55 °C-125 °C, delta C/C = ±30 ppm/°C) properties. The measured values of equivalent series resistance and equivalent series inductance were 6.1 ω and 62.39 μH, respectively. The leakage current density was 0.78 μA/cm2 at 3 V of applied voltage. These electrical properties indicate that the CSZT embedded capacitor holds promise for use as an embedded passive capacitor.
