Abstract: A method includes applying a die attach material to a die pad of an integrated circuit package. The die attach material is employed as a bonding material to the die pad. The method includes mounting an integrated circuit die to the die pad of the integrated circuit via the die attach material. The method includes printing an adhesion deposition material on the die attach material appearing at the interface of the integrated circuit die and the die pad of the integrated circuit package to mitigate delamination between the integrated circuit die and the die pad.

Abstract: A device comprises a substrate and an adhesive nanoparticle layer patterned into zones of electrical conductance and insulation on top of the substrate surface. A diffusion region adjoining the surface comprises an admixture of the nanoparticles in the substrate material. When the nanoparticle layer is patterned from originally all-conductive nanoparticles, the insulating zones are created by selective oxidation; when the nanoparticle layer is patterned from originally all-non-conductive nanoparticles, the conductive zones are created by depositing selectively a volatile reducing agent. A package of insulating material is in touch with the nanoparticle layer and fills any voids in the nanoparticle layer.

Abstract: A method of lead frame surface modification includes providing at least one pre-fabricated metal lead frame or package substrate (substrate) unit including a base metal having a die pad and a plurality of contact regions surrounding the die pad. An ink including a material that is a solid or a precursor for a solid that forms a solid upon a curing step or a sintering step that removes a liquid carrier is additively deposited including onto at least one of (i) a region of the die pad and (ii) at one region of at least a first of the contact regions (first contact region). The ink is sintered or cured to remove the liquid carrier so that a substantially solid ink residue remains.
