A method for forming a chip package structure is provided. The method includes disposing a chip over a substrate. The method includes forming a heat-spreading wall structure over the substrate. The heat-spreading wall structure is adjacent to the chip, and there is a first gap between the chip and the heat-spreading wall structure. The method includes forming a first heat conductive layer in the first gap. The method includes forming a second heat conductive layer over the chip. The method includes disposing a heat-spreading lid over the substrate to cover the heat-spreading wall structure, the first heat conductive layer, the second heat conductive layer, and the chip. The heat-spreading lid is bonded to the substrate, the heat-spreading wall structure, the first heat conductive layer, and the second heat conductive layer.

A semiconductor package structure is provided. The semiconductor package structure includes a carrier substrate, an interposer substrate, a semiconductor device, a lid, and a thermal interface material. The interposer substrate is disposed on the carrier substrate. The semiconductor device is disposed on the interposer substrate. The lid is disposed on the carrier substrate to cover the semiconductor device. The thermal interface material is disposed between the lid and the semiconductor device. A first recess is formed on a lower surface of the lid facing the semiconductor device, and the first recess overlaps the semiconductor device in a top view.
