Classification: CPC H | IPC H

Claim 19:
20. The method according to claim 18, wherein the forming a heat dissipation conduit comprises:
forming a first conductive structure at a first height in the region, wherein the first height enables the first conductive structure to be located at substantially the same height as a corresponding component;
forming a first dielectric material in the region so as to bury the first conductive structure, wherein a top surface of the first dielectric material is located at a second height, wherein the second height enables a second conductive structure subsequently formed on the first dielectric material to be located at substantially the same height as a corresponding component;
forming a first opening with a first width in the first dielectric material;
forming a lateral channel under the first opening by etching through the first opening, wherein the lateral channel has a second width greater than the first width;
forming a first plug in the first opening;
forming a second conductive structure on the first dielectric material;
forming a second dielectric material in the region, wherein a top surface of the second dielectric material is located at a third height;
forming a second opening in the second dielectric material; and
forming vertical channels in communication with two opposite ends of the lateral channel by etching through the second opening.
