The present invention relates generally to testing of interconnects in a semiconductor die, and more particularly to testing of semiconductor chips that are three-dimensionally stacked via an interposer. In one aspect, a method for testing an interconnect in a semiconductor die comprises providing the semiconductor die, which includes a plurality of electrical contact elements formed at one or more surfaces of the semiconductor die, at least one interconnect-under-test disposed between a first electrical contact element and a second electrical contact element, and an electrical component electrically coupled between the interconnect-under-test and at least one third electrical contact element.
