Three-dimensional integrated circuit

Abstract

A three-dimensional integrated circuit, including a first adhesive bonding layer, a first chip, a second chip, and an inter-stratum thermal pad, is provided. The first adhesive bonding layer has a first surface and a second surface opposite to each other. The first chip is disposed on the first surface of the first adhesive bonding layer. The first chip includes a hot zone. The second chip is disposed on the second surface of the first adhesive bonding layer. The inter-stratum thermal pad is embedded in the first adhesive bonding layer and faces to the hot zone.
