发明名称 Semiconductor interconnect having semiconductor spring contacts
摘要 An interconnect for testing a semiconductor component includes a substrate, and interconnect contacts on the substrate configured to electrically engage component contacts on the component. The interconnect contacts include flexible spring segments defined by grooves in the substrate, shaped openings in the substrate, or shaped portions of the substrate. The spring segments are configured to flex to exert spring forces on the component contacts, and to compensate for variations in the size or planarity of the component contacts. The interconnect can be configured to test wafer sized components, or to test die sized components. A test method includes the steps of providing the interconnect with the interconnect contacts, and electrically engaging the component contacts under a biasing force from the spring segments. A wafer level test system includes the interconnect mounted to a testing apparatus such as a wafer probe handler. A die level test system includes the interconnect mounted to a test carrier for discrete components.
