A method of making a multilayered, fusion bonded circuit structure. A first circuitry layer is attached to a first major surface of a first LCP substrate. A plurality of first recesses are formed that extend from a second major surface of the first substrate to the first circuitry layer. The first recesses are then plated to form a plurality of first conductive pillars of solid metal that substantially fill the first recesses. A plurality of second recesses are formed in a second LCP substrate corresponding to a plurality of the first conductive pillars. The second recess are plated to form a plurality of second conductive structures that extend between first and second major surfaces of the second substrate. The second major surface of the first substrate is positioned adjacent to the second major surface of the second substrate. The first conductive pillars are aligned with the second conductive structures. The stack is then fusion bonded to mechanically couple the first conductive pillars to the second conductive structures.

Methods capable of forming holes in, etching the surface of, or otherwise ablating substrates, and substrates formed thereby. A first method includes directing a first laser beam pulse towards a substrate to form a hole in a surface thereof and to form a plasma plume at least partially within the hole wherein the plasma plume has insufficient thermal energy and expansion velocity to etch sidewall of the hole, and directing a second laser beam pulse into the plasma plume to increase the temperature and expansion velocity of the plasma plume such that the sidewall is etched causing an increase in the cross-sectional dimension of the hole. A second method includes applying a liquid to a surface of a substrate, and directing a laser beam pulse into the liquid to create plasma on the surface of the substrate that etches portions of the surface of the substrate.
