In one example, a semiconductor device comprises an electronic component comprising a component face side, a component base side, a component lateral side connecting the component face side to the component base side, and a component port adjacent to the component face side, wherein the component port comprises a component port face. A clip structure comprises a first clip pad, a second clip pad, a first clip leg connecting the first clip pad to the second clip pad, and a first clip face. An encapsulant covers portions of the electronic component and the clip structure. The encapsulant comprises an encapsulant face, the first clip pad is coupled to the electronic component, and the component port face and the first clip face are exposed from the encapsulant face. Other examples and related methods are also disclosed herein.
