MULTI-LAYER CERAMIC SUBSTRATE AND METHOD OF MANUFACTURING THE SAME

摘要

A multi-layer ceramic substrate and a method for manufacturing the same are provided to improve quality and reliability of the multi-layer ceramic substrate by removing fine crack, warpage, and separation phenomena by including a via bridge unit. A multi-layer ceramic substrate includes a ceramic substrate main body unit, at least one material layer(115), and at least one via bridge unit(119). The ceramic substrate main body unit is stacked with a plurality of ceramic layers(111,113) including first materials respectively. At least one material layer includes a second material different from the first material by being interposed between the plurality of ceramic layers. The via bridge unit includes a via hole(117) formed on at least one material layer and a material joined to the adjacent material layer and filled inside the via hole. The filling material of the via bridge unit has a larger junction strength than the strength of a material of the material layer to a material of the ceramic layers.
