Abstract:
A method of packaging a semiconductor device having a bond pad on a surface thereof includes forming a redistribution material electrically coupled to the bond pad, forming a dielectric material over the redistribution material, and removing a first portion of the dielectric material to expose a first portion of the redistribution material. Semiconductor packages may include a redistribution layer having a first portion adjacent and coupled to a first contact of the package, a second portion exposed by a first opening in a dielectric material, and a redistribution line electrically coupled to a first bond pad, the first portion, and the second portion. Such a package may be tested placing at least one probe needle in contact with at least one terminal of the package, providing a test signal from the probe needle to the package through the terminal, and detecting signals using the needle.
