Abstract
In one embodiment, a probe for testing integrated circuits includes a body having a tip and a hardening material on the tip. The hardening material helps improve the hardness of the tip. The hardening material thus allows the probe to reliably penetrate a layer to make a good electrical connection with a contact point under the layer, for example. In one embodiment, an electrically conductive coating is deposited over the hardening material.
