ABSTRACT:
The invention encompasses a board-on-chip package comprising an insulative substrate having circuitry thereon and an opening therethrough. A semiconductive-material-comprising die is adhered to the substrate and electrically connected to the circuitry with a plurality of electrical interconnects extending through the opening. A metal foil is in physical contact with at least a portion of the die. The invention also encompasses a method of forming a plurality of board-on-chip packages. An insulative substrate is provided. Such substrate has a repeating circuitry pattern thereon, and a plurality of openings therethrough. The openings are in a one-to-one correspondence with individual of the repeated circuitry patterns. A plurality of semiconductive-material-comprising dies are adhered to the substrate. Circuitry supported by the dies is electrically connected with the circuitry on the substrate utilizing a plurality of electrical interconnects extending through the openings. A metal foil is joined to the substrate and extended over the plurality of dies. The substrate and metal foil are cut to form singulated die packages comprising a single die, a portion of the substrate having a single repeated pattern of the circuitry, and a portion of the metal foil.
