A method for forming an interposer comprises forming a fill hole in a first side of a substrate and a cavity in a second side of the substrate. The cavity is in fluidic communication with the fill hole. A plurality of posts is formed in the cavity. An encapsulant is injected through the fill hole into the cavity to encapsulate the plurality of posts.</p>
