Porous Circuitry Material for Led Submounts

摘要

A submount comprising a ceramic substrate and a circuitry arranged thereon is provided. The circuitry comprises an electrically conducting porous material comprising at least one noble metal doped with at least one non-noble metal, the surface of at least portions of said electrically conducting porous material comprises oxides of said non-noble metals, and said ceramic substrate is bonded to said porous electrically conducting material via said oxides of said non-noble metals.
