Abstract

A method of forming an assembly is provided. The method includes attaching a packaged semiconductor device to a substrate. An isolation structure is formed and located between the packaged semiconductor device and the substrate. An underfill material is dispensed between the packaged semiconductor device and the substrate. The isolation structure prevents the underfill material from contacting a first conductive connection formed between the packaged semiconductor device and the substrate.
