Abstract
A semiconductor package comprises a semiconductor substrate that may comprise a core. The core may comprise one or more materials selected from a group comprising ceramics and glass dielectrics. The package further comprises a set of one or more inner conductive elements that is provided on the core, a set of one or more outer conductive elements that is provided on an outer side of the substrate, and a semiconductor die to couple to the substrate via one or more of the outer conductive elements. Example materials for the core may comprise one or more from alumina, zirconia, carbides, nitrides, fused silica, quartz, sapphire, and Pyrex. A laser may be used to drill one or more plated through holes to couple an inner conductive element to an outer conductive element. A dielectric layer may be formed in the substrate to insulate an outer conductive element from the core or an inner conductive element.
