Abstract:
1. A method for forming an electronic structure, comprising: providing a substrate; forming a first circuit line including a first portion and a second portion, wherein the second portion of the first circuit consists of a first conductive pad, wherein the first portion of the first circuit line has a first thickness extending in a direction perpendicular to a surface of the substrate at which the first circuit line is coupled to the substrate, and wherein the first circuit line is totally external to an interior of the substrate and is in direct surface-to-surface contact with the substrate; forming a second circuit line including a first portion and a second portion, wherein the second portion of the second circuit line consists of a second conductive pad, wherein the first portion of the second circuit line has a second thickness extending in the direction perpendicular to the surface of the substrate at which the second circuit line is coupled to the substrate, wherein the second circuit line is electrically coupled to the first circuit line, wherein the second thickness is unequal to the first thickness, and wherein the second circuit line is totally external to the interior of the substrate and is in direct surface-to-surface contact with the substrate; coupling a third circuit line to the substrate, wherein the third circuit line has a third thickness that is unequal to both the first thickness and the second thickness, wherein a portion of the third circuit line is electrically coupled to a portion of the first circuit line, wherein a portion of the third circuit line is electrically coupled to a portion of the second circuit line, wherein the third thickness extends in the direction perpendicular to the surface of the substrate at which the third circuit line is coupled to the substrate, wherein the third circuit line is totally external to the interior of the substrate and is in direct surface-to-surface contact with the substrate, wherein the third circuit line physically touches the first circuit line in direct surface-to-surface contact, and wherein the third circuit line physically touches the second circuit line in direct surface-to-surface contact; coupling an electronic assembly to the first conductive pad; and coupling an electronic carrier to the second conductive pad.
