One or more embodiments are directed to quad flat no-lead (QFN) semiconductor packages, devices, and methods in which one or more electrical components are positioned between a die pad of a QFN leadframe and a semiconductor die. In one embodiment, a device includes a die pad, a lead that is spaced apart from the die pad, and at least one electrical component that has a first contact on the die pad and a second contact on the lead. A semiconductor die is positioned on the at least one electrical component and is spaced apart from the die pad by the at least one electrical component. The device further includes at least one conductive wire, or wire bond, that electrically couples the at least one lead to the semiconductor die.

SMDs integration on QFN by 3D stacked solution

One or more embodiments are directed to semiconductor packages and methods in which one or more electrical components are positioned between a semiconductor die and a surface of a substrate. In one embodiment, a semiconductor package includes a substrate having a first surface. One or more electrical components are electrically coupled to electrical contacts on the first surface of the substrate. A semiconductor die is positioned on the one or more electrical components, and the semiconductor die has an active surface that faces away from the substrate. An adhesive layer is on the first surface of the substrate and on the one or more electrical components, and the semiconductor die is spaced apart from the one or more electrical components by the adhesive layer. Wire bonds are provided that electrically couples the active surface of the semiconductor die to the substrate.

A first device includes a rectangular substrate having a first width and a first length and a first pattern of electrical interface nodes at first, second and third sides with a first set of electrical interface nodes at the fourth side. A second device includes a second rectangular substrate having a second width equal to the first width, a second length and a median line extending in the direction of the second width. A second pattern of electrical interface nodes for the second device includes two unmorphed replicas of the first pattern arranged mutually rotated 180&#xb0; on opposite sides of the median line as well as two second sets of electrical interface nodes formed by two smaller morphed replicas of the first set of electrical interface nodes arranged mutually rotated 180&#xb0; on opposite sides of said median line.
