Patent ID: 8722457

Claim:
A method of making a semiconductor device, comprising: providing a semiconductor wafer containing a plurality of first semiconductor die each having an active surface; forming an adhesive layer on the active surface of the first semiconductor die; providing a plurality of semiconductor packages by, (a) providing a leadframe for each semiconductor package, (b) mounting a second semiconductor die to a die pad on the leadframe, (c) forming a dam around the die pad, (d) forming a first bond wire between the second semiconductor die and a first contact pad on the leadframe, and (e) depositing a first encapsulant in contact with the second semiconductor die and leadframe; leading with the first encapsulant, mounting the semiconductor packages to the adhesive layer over the active surface of the first semiconductor die; forming a second bond wire between the first contact pad on the leadframe and a contact pad on the first semiconductor die; depositing a second encapsulant in contact with the semiconductor packages and semiconductor wafer, the dam preventing the second encapsulant from covering the die pad of the leadframe; forming a redistribution layer over a back surface of the first semiconductor die, opposite the active surface; forming a conductive via through the first semiconductor die to electrically connect the redistribution layer and contact pad of the first semiconductor die; forming a first bump on the redistribution layer; and singulating the semiconductor wafer into the individual first semiconductor die after mounting the semiconductor package, each semiconductor package being a known good unit which performs electrical functions in support of the first semiconductor die so that the active circuits in the first semiconductor die can be formed without the electrical functions performed by the semiconductor package.
