Embedded capacitor technology can improve electrical performanceand reduce assembly cost compared with traditional discrete capacitortechnology. Polymer-ceramic composites have been of great interest asembedded capacitor material because they combine the processability ofpolymers with the desired electrical properties of ceramics. A novelnano-structure polymer-ceramic composite with very high dielectricconstant (ετ=150) has been developed in this work.RF application of embedded capacitors requires that insulating materialhave high dielectric constant in higher frequency (GHz), low leakagecurrent, high breakdown voltage and high reliability. A set of electrictests have been conducted in this work to characterize the properties ofthe in house developed novel high dielectric constant polymer-ceramicnano-composite. Results show that this material has fair high dielectricconstant in RF range, low electric leakage and high breakdown voltage.An embedded capacitor prototype with capacitance density of 35nF/cm2 has been manufactured using this nano-composite andspinning coating technology. The design of embedded passives is veryimportant to its practical application. The commercial finite elementsoftware ANSYS and electric simulation software SPICE were used for thesimulation of embedded capacitor performance in the RF range. This novelnano-composite can be used for the integral capacitors in the RFapplications
