Abstract:
A method forming a packaged semiconductor device includes providing a first semiconductor die (first die) having bond pads thereon mounted face-up on a package substrate or on a die pad of a lead frame (substrate), wherein the substrate includes terminals or contact pads (substrate pads). A first dielectric layer is formed including printing a first dielectric precursor layer including a first ink having a first liquid carrier solvent extending from the substrate pads to the bond pads. A first interconnect precursor layer is printed including a second ink having a second liquid carrier over the first dielectric layer extending from the substrate pads to the bond pads. Sintering or curing the first interconnect precursor layer removes at least the second liquid carrier to form an electrically conductive interconnect including an ink residue which connects respective substrate pads to respective bond pads.
