Abstract:
Embodiments of resilient contact elements and methods for fabricating same are provided herein. In one embodiment, a resilient contact element for use in a probe card includes a lithographically formed resilient beam having a first end and an opposing second end; and a tip disposed proximate the first end of the beam and configured to break through an oxide layer of a surface of a device to be tested to establish a reliable electrical connection therewith; wherein at least a central portion of the beam has a continuous sloped profile defining, in a relaxed state, a height measured between the beam and a plane representing an upper surface of a device to be tested that is greater near the second end of the beam than near the first end of the beam.
