A copper-topped die, which has exposed copper lines and pads, is utilized as the lower die in a stacked die structure. A non-conductive material is formed over the lower copper-topped die, and then selectively removed so that the non-conductive material covers and lies between the copper lines while none of the non-conductive material lies over the copper pads. An upper die is then attached to the non-conductive material.
