Apparatuses for dissipating heat from semiconductor devices
First Claim
1. An apparatus for removing heat from a semiconductor structure, comprising:
- a top vapor chamber having a plurality of three-dimensional (3D) shaped members and disposed on top of the semiconductor structure;
a plurality of side vapor chambers each having another set of a plurality of three-dimensional (3D) shaped members, the side vapor chambers disposed to surround the semiconductor structure, the top vapor chamber and the side vapor chambers are configured to be fluidly coupled to enable transfer of fluid therebetween;
the side vapor chambers are mounted at an angle to enable backflow of condensed fluid by gravity towards a base portion of the semiconductor structure, the base portion being in contact with a chip carrier; and
wherein the top vapor chamber and the side vapor chambers are filled with a coolant so as to completely cover sidewalls and top exterior surface of the structure in order to provide maximum surface contact and cooling capacity.

Abstract
An apparatus for providing two-phase heat transfer for semiconductor devices includes a vapor chamber configured to carry a cooling liquid, the vapor chamber having base section, and a plurality of three-dimensional (3D) shaped members. The plurality of 3D-shaped members have interior and exterior sidewalls, the 3D-shaped members being connected to the base section so that vapor carrying latent heat can reach the respective interior sidewalls and get transferred to the respective exterior sidewalls configured to be in contact with an external coolant. The vapor chamber is configured to be in contact with a semiconductor device in order to remove heat therefrom.
