A method of connecting a conductive trace to a semiconductor chip includes providing a semiconductor chip with upper and lower surfaces, wherein the upper surface includes a conductive pad, providing a conductive trace, then disposing an insulative adhesive between the conductive trace and the chip, thereby mechanically attaching the conductive trace to the chip such that the conductive trace overlaps the pad, the adhesive contacts and is sandwiched between the conductive trace and the pad, and the conductive trace and the pad are electrically isolated from one another, then removing the adhesive between the conductive trace and the pad, and then forming a connection joint that contacts and electrically connects the conductive trace and the pad. Preferably, the adhesive is removed by laser ablation then plasma etching.
