Abstract

An integrated circuit package includes a semiconductor chip having a passivation layer forming the top surface of the semiconductor chip and a metal pad formed on the passivation layer and a discrete electronic device having a first terminal formed on a first surface and a second terminal formed on a second surface opposite the first surface of the discrete electronic device where the first surface of the discrete electronic device is attached to the metal pad using a conductive adhesive structure. The semiconductor chip and the discrete electronic device are encapsulated in an encapsulation material. An electrical connection is formed between the metal pad and one of a bond pad of the semiconductor chip or a package post of the integrated circuit package. In one embodiment, the metal pad is an aluminum pad and a metal line connects the metal pad to a bond pad of the semiconductor chip.
