Abstract

A package structure and a formation method of a package structure are provided. The method includes disposing a chip structure over a substrate and forming a first adhesive element directly on the chip structure. The first adhesive element has a first thermal conductivity. The method also includes forming a second adhesive element directly on the chip structure. The second adhesive element has a second thermal conductivity, and the second thermal conductivity is greater than the first thermal conductivity. The method further includes attaching a protective lid to the chip structure through the first adhesive element and the second adhesive element.
