MULTILAYER CERAMIC SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a multilayer ceramic substrate and a method for manufacturing the same.SOLUTION: A multilayer ceramic substrate includes: a plurality of ceramic layers including a first pad electrode; an internal via formed in the ceramic layer so as to be electrically connected to the first pad electrode and formed of a material having a lower shrinkage start temperature than the ceramic layer; and an external via formed in the ceramic layer so as to cover an outer peripheral surface of the internal via. The external via includes a conductive material and an additive material diffused to the internal via side and added to the conductive material to reduce the burning speed of the internal via.
