Abstract
The present invention provides a multilayer ceramic composition comprising at least one layer of dielectric material M1 and at least one layer of dielectric material M2, wherein passive components are buried in both layers of dielectric material M1 and M2 that prevent each other from shrinkage in the X and Y dimensions during firing. Each layer of the multilayer ceramic composition according to the invention can be used as a substrate for burying the passive component and has the ability to prevent other layer with different dielectric constant from shrinkage. Hence, the multilayer ceramic composition has the advantages of smaller size and a better circuit precision.
