Abstract: The assembly of a chip (101) attached to a substrate (103) with wires (201) spanning from the chip to the substrate is loaded in a heated cavity (402) of a mold; the wire surfaces are coated with an adsorbed layer of molecules of a heterocyclic compound (302); a pressure chamber (404) of the mold is loaded with a solid pellet (410) of a packaging material including a polymerizable resin, the chamber being connected to the cavity; the vapor of resin molecules is allowed to spread from the chamber to the assembly inside the cavity during the time interval needed to heat the solid pellet for rendering it semi-liquid and to pressurize it through runners (403) before filling the mold cavity, whereby the resin molecules arriving in the cavity are cross-linked by the adsorbed heterocyclic compound molecules into an electrically insulating at least one monolayer of polymeric structures on the wire surfaces.

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 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.
