A semiconductor device has a plurality of semiconductor die or components mounted over a carrier. A leadframe is mounted over the carrier between the semiconductor die. The leadframe has a plate and bodies extending from the plate. The bodies of the leadframe are disposed around a perimeter of the semiconductor die. An encapsulant is deposited over the carrier, leadframe, and semiconductor die. A plurality of conductive vias is formed through the encapsulant and electrically connected to the bodies of the leadframe and contact pads on the semiconductor die. An interconnect structure is formed over the encapsulant and electrically connected to the conductive vias. A first channel is formed through the interconnect structure, encapsulant, leadframe, and partially through the carrier. The carrier is removed to singulate the semiconductor die. A second channel is formed through the plate of the leadframe to physically separate the bodies of the leadframe.

A semiconductor device has a substrate. A plurality of conductive vias is formed through the substrate. A conductive layer is formed over the substrate. An insulating layer is formed over conductive layer. A portion of the substrate is removed to expose the conductive vias. A plurality of vertical interconnect structures is formed over the substrate. A first semiconductor die is disposed over the substrate. A height of the vertical interconnect structures is less than a height of the first semiconductor die. An encapsulant is deposited over the first semiconductor die and the vertical interconnect structures. A first portion of the encapsulant is removed from over the first semiconductor die while leaving a second portion of the encapsulant over the vertical interconnect structures. The second portion of the encapsulant is removed to expose the vertical interconnect structures. A second semiconductor die is disposed over the first semiconductor die.

This disclosure relates to a new package concept that eliminates the need for epoxy or epoxy solder used in traditional clip/lead frame-based power packages. The disclosure overcomes this disadvantage in clip-based packages by depositing the interconnect structure directly to the bod pads. The formation of the interconnect done at lower temperature leads to lower stress induced onto the die. Another advantage of the present disclosure is that semiconductor dies packaged using a method according to the present disclosure will have smaller footprint as the pads are directly built up/deposited. Another advantage of the method according to the present disclosure is that it allows large scale, i.e., panel level processing. Such a panel may include multiple ICs, or transistor or any other semiconductor devices.
