Abstract
Disclosed is a multilayer ceramic substrate having an outer pad, for example an I/O pad, which is anchored to a middle pad of the multilayer ceramic substrate by a plurality of vias which in turn is anchored to an inner pad of the multilayer ceramic substrate by a second plurality of vias. The middle and outer pads and vias are made of high metal material, preferably 100% metal, so they won't adhere very well to the ceramic substrate. The inner pad is a composite metal/ceramic material which will bond very well to the ceramic substrate.
