Abstract

The invention discloses a semiconductor device heat dissipation structure and a preparation method thereof, the semiconductor device heat dissipation structure comprises a composite shell and a heat pipe arranged in the composite shell, and the composite shell comprises an integrated structure formed by sequentially superposing a heat absorption material layer, a transition material layer and a heat dissipation material layer; the transition material layer is formed by mutual diffusion of atoms of the heat absorption material layer and the heat dissipation material layer, a device installation part is arranged on the surface, located on one side of the heat absorption material layer, of the composite shell, the bottom face of the device installation part is used for arranging a semiconductor device, and a cavity used for circulation of a cooling medium is formed in the heat dissipation material layer, the composite shell and the pipe wall of the heat pipe are of an integrated structure, and the side, opposite to the bottom face of the device installation part, of the heat pipe extends towards the interior of the cavity. The semiconductor device heat dissipation structure is of an integrated structure and is not provided with a contact interface with high thermal resistance, heat generated by the semiconductor device can be rapidly dissipated through multiple heat dissipation means, the size of the semiconductor device heat dissipation structure is not increased, and the requirement of a miniaturized device can be met.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a heat dissipation structure of a semiconductor device and a preparation method thereof. Background technique [0002] With the further development of science and technology, semiconductor technology, information technology and other cutting-edge technology fields are developing towards high power, high integration and miniaturization, resulting in the continuous increase of the heat dissipated by the system, and the high power density semiconductor devices inside the system continue to challenge the limit of its cooling system. [0003] In the prior art, a simple air-cooled or liquid-cooled heat dissipation system is usually used to cool down semiconductor devices. The heat dissipation efficiency of this type of heat dissipation system is low, and the liquid-cooled heat dissipation system usually has multiple component structures. Different component structures There wil...
