Printed interconnects for semiconductor packages
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. |

Method of forming an interconnect structure having an air gap and structure thereof
A semiconductor device and method of manufacture are provided which utilize an air gap to help isolate conductive structures within a dielectric layer. A first etch stop layer is deposited over the conductive structures, and the first etch stop layer is patterned to expose corner portions of the conductive structures. A portion of the dielectric layer is removed to form an opening. A second etch stop layer is deposited to line the opening, wherein the second etch stop layer forms a stepped structure over the corner portions of the conductive structures. Dielectric material is then deposited into the opening such that an air gap is formed to isolate the conductive structures. |
