Abstract
Extension tips for lift-out probes used in conjunction with focused ion beam (FIB) systems and analytical instruments employing such probes are disclosed. Methods of forming the extension tips from a variety of materials such as a silicon wafer, preformed whiskers of conductive material, and metal lines or contacts removed from integrated circuits are also disclosed. Methods of using a variety of extension tips pre-placed within the FIB system to enable reconditioning worn or damaged lift-out probes are also disclosed.
