In one example, a semiconductor device comprises a main substrate comprising a first side and a main conductive structure, and a first component module over the first side of the main substrate. The first component module comprises a first electronic component and a first module encapsulant contacting a lateral side of the first electronic component. The semiconductor device further comprises a second component module over the first side of the main substrate. The second component module comprises a second electronic component and a second module encapsulant contacting a lateral side of the second electronic component. The semiconductor device further comprises a main encapsulant over a first side of the main substrate and between the first component module and the second component module. Other examples and related methods are also disclosed herein.
