Abstract:
1. A method of making a semiconductor device, comprising: providing a sacrificial carrier; forming a first conductive layer over the sacrificial carrier; mounting a backside of a first semiconductor die over the first conductive layer; forming a first conductive bump over a first contact pad of the first semiconductor die; forming a second conductive bump over a second contact pad of the first semiconductor die; forming a third conductive bump over the sacrificial carrier in proximity to the first semiconductor die; mounting first and second contact pads of a second semiconductor die over the second and third conductive bumps; forming a second conductive layer over a backside of the second semiconductor die opposite the first and second contact pads of the second semiconductor die; depositing an encapsulant over the first and second semiconductor die and first, second, and third conductive bumps; removing the sacrificial carrier; and removing a portion of the encapsulant to planarize the first conductive bump and the backside of the second semiconductor die and planarize the third conductive bump and the backside of the first semiconductor die.
