Claim Text:
1. A microelectronic component comprising: a substrate comprising a top surface, a bottom surface, and one or more first through-holes, each first through-hole passing between the top surface and the bottom surface; one or more conductive vias protruding from the one or more first through-holes to form at each first through-hole a conductive protrusion above the substrate; for each conductive protrusion protruding from a corresponding first through-hole, a first conductive sleeve region wrapping around the conductive protrusion and extending at least along a segment of the conductive protrusion, the first conductive sleeve region being electrically insulated from any conductive protrusion protruding from the first through-hole above the substrate, the first conductive sleeve region comprising an inner surface facing the conductive protrusion, an outer surface opposite to the inner surface, and a thickness which is a distance between the inner and outer surfaces, a maximum value of the thickness being smaller than a length of the inner surface measured along the segment.
