Abstract

An interconnect and system for testing semiconductor dice, and a test method using the interconnect are provided. The interconnect includes a substrate having patterns of contact members for electrically contacting the dice. The interconnect also includes patterns of conductors for providing electrical paths to the contact members. In addition, the interconnect includes contact receiving cavities configured to retain electrical connectors of a testing apparatus in electrical communication with the conductors. A die level test system includes the interconnect mounted to a temporary package for a singulated die. In the die level test system, the interconnect provides direct electrical access from testing circuitry to the die. A wafer level test system includes the interconnect mounted to a probe card fixture of a wafer probe handler. In the wafer level test system, the contact receiving cavities can be configured to support and align the interconnect to the probe card fixture.
