Abstract
Disclosed is a multilayer ceramic substrate having an outer pad, for example an I/O pad, which is anchored to an inner pad of the multilayer ceramic substrate by either a plurality of vias or one large via. The outer pad 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.
