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.
