Abstract:
A chip package including a lead frame, a first chip, a heat dissipation structure, and an insulating encapsulant is provided. The lead frame includes a chip pad having a first surface and a second surface opposite to the first surface and a lead connected to the chip pad. The first chip is disposed on the first surface of the chip pad and electrically connected to the lead of the lead frame and to the outside of the insulating encapsulant via the lead. The head dissipation structure is disposed on the second surface of the chip pad and includes a thermal interface material layer attached to the second surface. The insulating encapsulant encapsulates the first chip, the heat dissipation structure, and a portion of the lead frame.

Claim (Index 8):
A chip package, comprising:\n a lead frame having a first surface and a second surface opposite to the first surface, wherein the lead frame comprises a lead; a chip disposed on the first surface of the lead frame and electrically connected to the lead frame; a heat dissipation stack structure disposed on the second surface of the lead frame, comprising: a first thermal interface material layer comprising a top surface facing the chip; and a second thermal interface material layer located between the lead frame and the first thermal interface material layer and covering the top surface of the first thermal interface material layer, wherein the second thermal interface material layer comprises a top surface connected to the second surface of the lead frame and a bottom surface opposite to the top surface, and an area of the top surface of the first thermal interface material layer is equal to an area of the bottom surface of the second thermal interface material layer and greater than an area of the top surface of the second thermal interface material layer; and an insulating encapsulant encapsulating the chip, the heat dissipation stack structure, and the lead frame, wherein the lead of the lead frame is extended out from within the insulating encapsulant.
