Interposers, electronic modules, and methods for forming the same

摘要

An interposer comprises a substrate and a plurality of posts. Each of the posts extends substantially through a thickness of the substrate. 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.
