A semiconductor device package structure is provided, which includes a substrate, one or more dies coupled to the substrate, and a heat pipe device. In an example, the heat pipe device may include a conduit that is at least partially embedded within the substrate. The heat pipe device may have a first region coupled to the one or more dies. In an example, the conduit may include a first path for flow of vapor from the first region to an opposing second region. The conduit may further include a second path for flow of liquid from the second region to the first region.
