Abstract
The invention relates to a high-dielectric constant metal/ceramic/polymer composite material and a method for producing an embedded capacitor.As ceramic particles having a relatively small size are bound to the surface of metal particles having a relatively large size by mixing, the occurrence of percolation can be prevented without coating the metal particles, and at the same time, the capacitance of an embedded capacitor can be increased. In addition, a process for coating the surface of the metal particles can be omitted, thus contributing to the simplification of the overall preparation procedure.
