Abstract:
A substrate for mounting microelectronic components, comprising:a generally planar support base having an electrically conductive upper surface, a plurality of mesas having respective tops and respective bottoms, said bottoms being positioned on said support base, the tops of said mesas being substantially coplanar with the upper surface of said planar support base, made of a conductive material and electrically coupled to said conductive upper surface of said support base;a dielectric layer having a thickness and covering the side walls of said mesas and the conductive upper surface of said support base between and surrounding said mesas, the thickness of said dielectric layer being substantially less than the height of said mesas; anda conductive layer positioned over said dielectric layer between and surrounding said mesas, said conductive layer having a planar upper surface which is substantially coplanar with the tops of said mesas and being electrically isolated from said mesas by said dielectric material.
